Chapter 1 – Introduction RPV311

2 Product Scope
The processing unit RPV311 and the acquisition modules RA331, RA332, and RA333 offer a distributed solution for
Multifunction Digital Recording. The solution is designed for the acquisition, monitoring and recording of electrical quantities
normally associated with electrical power generation, transmission, or distribution equipment. It is the solution for
applications which require flexibility, allowing installation of RPV311 Processing Unit in existing panels and the Acquisition
Modules RA331, RA332, and RA333 near to the plant seeing monitored the applications installation.
The RPV311Solution is a multifunction equipment with fan-less and no rotating part design. It has an acquisition system with
16-bit A/D D converters that provide an acquisition rate of 256 points-per-cycle synchronized by the IRIG-B signal.
It has a high processing capability, which allows the acquisition of up to 64 analog channels and 256 digital channels divided
in up to 8 acquisition modules connected by fiber-optic links. Additionally, it is able to detect IEC 61850 GOOSE messages.
It allows communication through the electrical Ethernet ports and optionally has a double internal converter for optical
Ethernet interfaces.
Monitoring and configuration are performed through RPV311 Configurator; also, it has a human-machine interface on the
front panel for displaying information. It has a MODBUS and DNP3 interface for SCADA integration.
The RA331 module allows data acquisition of up to 8 analogue channels (voltage, current, or DC transducers) and up to 32
digital channels. The RA332 module allows data acquisition of up to 16 analogue channels (voltage, current, or DC
transducers) and up to 32 digital channels. Both modules use 16-bit A/D converters providing an acquisition rate of 256
points-per-cycle.
The RA333 module allows data acquisition of high-speed analog channels (voltage) for one transmission line. This module
allows the scheme to obtain traveling wave records for fault locating. Additionally, the RA333 module allows data acquisition
of up to 8 analog channels (voltage, current, or DC transducers) and up to 16 digital channels, using 16-bit A/D converters
providing an acquisition rate of 256 points-per-cycle.

3 Installation, Commissioning and Servicing

3.1 Lifting Hazards

Many injuries are caused by:
• Lifting heavy objects
• Lifting things incorrectly
• Pushing or pulling heavy objects
• Using the same muscles repetitively
Plan carefully, identify any possible hazards and determine how best to move the product. Look at other ways of moving the
load to avoid manual handling. Use the correct lifting techniques and Personal Protective Equipment (PPE) to reduce the risk
of injury.

3.2 Electrical Hazards

All personnel involved in installing, commissioning, or servicing
this equipment must be familiar with the correct working
procedures.

Consult the equipment documentation before installing,

commissioning, or servicing the equipment.

Always use the equipment as specified. Failure to do so will

jeopardize the protection provided by the equipment.

RPV311-TM-EN-13.1A 29
RPV311 Chapter 2 – Safety Information

Removal of equipment panels or covers may

expose hazardous live parts. Do not touch until the
electrical power is removed. Take care when there
is unlocked access to the rear of the equipment.

Isolate the equipment before working on the

terminal strips.

Use a suitable protective barrier for areas with

restricted space, where there is a risk of electric
shock due to exposed terminals.

Disconnect power before disassembling. Disassembly of the

equipment may expose sensitive electronic circuitry. Take
suitable precautions against electrostatic voltage discharge (ESD)
to avoid damage to the equipment.

NEVER look into optical fibers or optical output connections.

Always use optical power meters to determine operation or signal
level.

Testing may leave capacitors charged to dangerous voltage levels.

Discharge capacitors by reducing test voltages to zero before
disconnecting test leads.

If the equipment is used in a manner not specified by the

manufacturer, the protection provided by the equipment may be
impaired.

Operate the equipment within the specified electrical and

environmental limits.

Before cleaning the equipment, ensure that no connections are

energized. Use a lint free cloth dampened with clean water.

Integration of the equipment into systems shall not interfere with

its normal functioning.

The functioning of the device has been certified under the

circumstances described by the standards mentioned in
Chapter 17: Technical Specifications (item Type Tests). Usage of
the equipment in different conditions from the specified in this
manual might affect negatively its normal integrity.

30 RPV311-TM-EN-13.1A
Chapter 2 – Safety Information RPV311

The equipment shall have all their rear connectors attached even
if they are not being used, in order to keep their levels of ingress
protection as high as possible

Never manipulate liquid containers near the equipment even

when it is powered off.

Avoid modification to the wiring of panel when the system is

running.

VT circuits must never be left short circuited.

3.3 Fusing and Insulation Requirements

A high rupture capacity (HRC) fuse type with a maximum current

rating of 10 Amps and a minimum dc rating of 250 V dc may be
used for the auxiliary supply (for example Red Spot type NIT or
TIA). Alternatively a miniature circuit breaker (MCB) of type C,
10A rating, compliant with IEC 60947-1 and IEC 60947-3 may be
used.

Digital input circuits should be protected by a high rupture

capacity NIT or TIA fuse with maximum rating of 10 A, or
equivalent MCB as above. For safety reasons, current transformer
circuits must never be fused. Other circuits should be
appropriately fused to protect the wire used.

Reason devices contain an internal fuse for the power supply

which is only accessed by opening the product. This does not
remove the requirement for external fusing or use of an MCB as
previously mentioned. The ratings of the internal fuses are:
RPV unit: 5 Amp, type T, 250V rating
RA units: 2 Amp, type T, 250V rating

CTs must NOT be fused since open circuiting them may produce
lethal hazardous voltages.

RPV311-TM-EN-13.1A 31
RPV311 Chapter 2 – Safety Information

3.4 Equipment Connections

Terminals exposed during installation, commissioning and

maintenance may present a hazardous voltage unless the
equipment is electrically isolated.

Tighten M3 clamping screws of heavy duty terminal block

connectors to a nominal torque of 1.0 Nm.
Tighten captive screws of header-type (Euro) terminal blocks to
0.5 Nm minimum and 0.6 Nm maximum.

Always use insulated crimp terminations for voltage and current

connections.

Always use the correct crimp terminal and tool according to the
wire size.

In order to maintain the equipment’s requirements for

protection against electric shock, other devices connected to the
RPV311 and RA33x shall have protective class equal or superior
to Class I.

Watchdog (self-monitoring) contacts are provided to indicate

the health of the device on some products. We strongly
recommend that you hard wire these contacts into the
substation's automation system, for alarm purposes.

Earth the equipment with the supplied PCT (Protective

Conductor Terminal).

Do not remove the PCT.

The PCT is sometimes used to terminate cable screens. Always

check the PCT’s integrity after adding or removing such earth
connections.

The user is responsible for ensuring the integrity of any

protective conductor connections before carrying out any
other actions.

The PCT connection must have low-inductance and be as short

as possible. For best EMC performance, ground the unit using
a 10 mm (0.4 inch) wide braided grounding strap.

32 RPV311-TM-EN-13.1A
Chapter 2 – Safety Information RPV311

All connections to the equipment must have a defined

potential. Connections that are pre-wired, but not used,
should be earthed, or connected to a common grouped
potential.

Pay extra attention to diagrams before wiring the equipment.

Always be sure that the connections are correct before
energizing the circuits.

The connections: Console1, Console2, MODEM and Process

bus are non-isolated and for local connection only.
Note: in HW-E those ports were removed.

3.5 Pre-energization Checklist

Check voltage rating/polarity (rating label/equipment

documentation).

Check CT circuit rating (rating label) and integrity of

connections.

Check protective fuse or miniature circuit breaker (MCB)

rating.

Check integrity of the PCT connection.

Check voltage and current rating of external wiring,

ensuring it is appropriate for the application.

RPV311-TM-EN-13.1A 33
RPV311 Chapter 2 – Safety Information

3.6 Peripheral Circuitry

Do not open the secondary circuit of a live CT

since the high voltage produced may be lethal to
personnel and could damage insulation. Short
the secondary of the line CT before opening any
connections to it.

Reason devices DO NOT feature any automatic CT shorting feature. Therefore

external shorting of the CTs is mandatory. Check the equipment documentation
and wiring diagrams carefully.

Where external components such as resistors or voltage

dependent resistors (VDRs) are used, these may present a
risk of electric shock or burns if touched.

Operation of computers and equipment connected to

RPV311 and RA33x under environmental conditions such
as temperature and humidity that exceed the conditions
specified in their respective manuals can cause
malfunctioning or even irreversible damage to them or the
nearby installation.

There might be situations in which the RPV311 and RA33x

are operating within its environmental operational range,
but the computers, equipment connected to them or
nearby equipment are operating outside their operational
range. That situation can cause malfunctioning and/or
irreversible damage to those devices. In that occasion the
communication to the Reason equipment might be
compromised but its recording, operational and safety
capacities will not be affected.

Take extreme care when using external test blocks and

test plugs such as the MMLG, MMLB and P990, as
hazardous voltages may be exposed. Ensure that CT
shorting links are in place before removing test plugs, to
avoid potentially lethal voltages.

34 RPV311-TM-EN-13.1A
Chapter 2 – Safety Information RPV311

3.7 Upgrading/Servicing

Do not insert or withdraw modules, PCBs or expansion

boards from the equipment while energized, as this
may result in damage to the equipment. Hazardous
live voltages would also be exposed, endangering
personnel.

Internal modules and assemblies can be heavy

and may have sharp edges. Take care when
inserting or removing modules into or out of
the IED.

4 Decommissioning and Disposal

Before decommissioning, completely isolate
the equipment power supplies (both poles of
any DC supply). The auxiliary supply input
may have capacitors in parallel, which may
still be charged. To avoid electric shock,
discharge the capacitors using the external
terminals before decommissioning.

Avoid incineration or disposal to water

courses. Dispose of the equipment in a safe,
responsible and environmentally friendly
manner, and if applicable, in accordance with
country-specific regulations.

The RA333 module allows data acquisition of high-speed analog channels (voltage) for one transmission line. This module
allows the scheme to obtain traveling wave records for fault locating. Additionally, the RA333 module allows data acquisition
of up to 8 analog channels (voltage, current, or DC transducers) and up to 32 digital channels, using 16-bit A/D converters
providing an acquisition rate of 256 points-per-cycle.

1.1 Processing Capability

The RPV311 has 8 link connections to communicate with RA33x acquisition units. As each acquisition unit has different
number of channels and functions, they require different levels of demand from the RPV311. In order to respect the RPV311
processing capability the number of RA33x that can be connected to the RPV311 obey the following rule:
The RPV311 can process 12 logical slots and each RA demands the following number of slots.

Device Logic Demand (slots)

RA331 1
RA332 2
RA333 DFR 1
RA333 TW 2

The user can combine the RA units as long as the logical sum of the slots value of each RA do not exceed the maximum
number of 12.

Note:
Differently from the RA331/332 the RA333 has two link: One for the DFR
functionality and another for the TW functionality.

Chapter 4 – Configuration RPV311

2 Equipment

2.1 Identification
On this screen, shown below, it is possible to configure the equipment identifier, location and owner.
These three fields make up the equipment file name pursuant to the COMNAME rule.
The equipment identification will appear in the name of the records; therefore, it is very important that it be properly
identified. The name format of the records is:

date,hour,location,identifier,owner...

Figure 10: Equipment identification configuration section

A The IDENTIFIER text field allows user to enter an equipment code (maximum 12 characters).

B The LOCATION text field allows user to enter a substation code (maximum 12 alphanumeric characters, _ , − , 0
, 0-9 , a-z , A-Z)

C The OWNER text field allows user to enter the name of the company which purchased the equipment
(maximum 12 characters).

2.2 Synchronization
If the IRIG-B signal has the CF extensions (IEEE1344), timing information as date, hour, year, time zone and daylight saving
time can be provided by the signal. Time zone and daylight saving time information can also be manually set via the RPV311
Configurator, overriding the information of the IRIG-B signal.

2.2.1 Time Source

On the screen TIME SOURCE it is possible to configure how the RPV311 will interpret the time zone of the IRIGB signal and also
the IP address of the NTPv2, 3 or 4 server.
The configurable settings are:
46 RPV311-TM-EN-13.1A
RPV311 Chapter 4 – Configuration

A Synch Source: Allows to user to choose between the IRIG-B signal or No Source.

B The TIMEZONE defines if time zone information is supplied by the IEEE1344 extensions of the IRIG-B signal, or if
it is manually set. This option will allow the RPV311 to identify the UTC time using information from the signal
or from the manual configuration of the user:

▪ When Auto (IRIGB with extensions) is selected the RPV311 shall use the information of time zone sent within the
IRIGB signal to recover the UTC time.

▪ When Manual is selected the RPV will not consider eventual time zones within the IRIGB signal, and rather it will
use the UTC time zone configured in the Manual parameter to retrieve the UTC time. This option is used specially
when the IRIGB does not inform the time zone, so the RPV311 cannot retrieve the UTC time unless we inform the
time zone manually.

The time setting that the RPV will use for time stamping is configured on the screen Internal Clock.

It is possible to configure 30 min time zones.

C The NTP FALLBACK SERVER defines the IP address of the SNTP time server to be used to provide time
synchronism when the IRIG-B is not connected.

2.2.2 Internal Clock

On the screen the internal clock for time stamping the registers and logs is configured, as well as day light saving
configurations. The configurable settings are:

A The TIMEZONE defines if time zone information is supplied by the IEEE1344 extensions of the IRIG-B signal, or if
it is manually set.

▪ When Auto is selected the RPV311 will use the same local time sent within the IRIGB signal.

▪ When Manual is selected the RPV311 will use the UTC time (retrieved using information from the Time Source
screen) and calculate the local time using the UTC time zone configured on the Internal Clock screen.

B The DAYLIGHT SAVING TIME defines if time information is supplied by IEEE1344 extensions of the IRIG-B signal, or
if it is either manually set or disabled. If it is manually set, it is possible to choose the date and time of the start
and the end of the DST period.

It is possible to configure 30 min time zones.

2.3 Communications
The RPV311 communication may be via Ethernet and serial ports. The equipment may also operate as a gateway over a local
subnet.
Optionally the user can choose between two types of Ethernet, optical and electrical.
Gateway setup will enable the RPV311 to communicate with other equipment connected over a local subnetwork. The
Gateway can be configured by accessing the equipment gateway configuration section, shown in Figure 11.

B The SPEED scroll box allows user to select the speed: 4800, 9600, 19200, 57600 or 115200 bps.

C The USE THIS PORT FOR ROUTING check box enables the use of the equipment as a router for another network.

D The MODEM check box allows permanent communication between an RPV311 and a server through a
telephone line.

E The DIAL OUT NUMBER text field allows user to enter a number to be dialed via modem. This can be left blank if a
direct serial communication link is used.

F The MODEM INIT STRING text field allows user to enter a string of characters which will be sent to the modem
before any communication is attempted. This can be left blank.

2.4 Acquisition with remote acquisition modules

The RPV311 data acquisition can be performed by the RA331, RA332 and RA333 remote acquisition modules.
The RA333 module consists of two different acquisition systems. One, called DFR, is used for analog data acquisition of
50/60 Hz of voltage, current, or DC. The other, called TW, is used for high-speed acquisition of traveling waves. The RA333
(TW) and RA333 (DFR) are physically installed in the same module, but are logically independent, i.e., the RPV311 will be
treated as two logical modules.
The RA331, RA332 and RA333 (DFR) modules are independent and use 16-bit opto-isolated A/D converters with
simultaneous acquisition of all channels provided by the IRIG-B signal, thus ensuring that the frequency acquisition is kept
constant.

RPV311-TM-EN-13.1A 49
Chapter 4 – Configuration RPV311

The analog channels for current measurement use internal shunts to minimize the effects of phase variation caused by
transformers.
There is a delay in the data transmission of the acquisition module for the processing module proportional to the length of
the fiber-optic cable. This delay is compensated by the RPV311 considering the information of the fiber length specified in
the configuration of the equipment.
The links should be installed of positions A to L. Intermediate empty positions are considered as "using" 8 analog channels.
Each link must be configured considering the module type and its inputs.
To configure the links, access the LINKS section, shown in Figure 13.

Figure 13: Links between RPV and acquisition modules configuration section
A The Position represents the position where the acquisition module is physically connected to the RPV311.
Positions A to L.

B The Module scroll box allows user to select the acquisition module used in the link and its characteristics
based on the Part Number of the module. The modules can be:RA331: Acquisition module with up to 8 analog
(voltage, current, or DC) and 32 digital channels;

RA332: Acquisition module with up to 16 analog (voltage, current, or DC) and 32

digital channels;
RA333 (TW): High frequency acquisition module with 3 high-speed analog channels
for acquisition of the traveling waves;
RA333 (DFR): Acquisition module with up to 8 analog (voltage, current, or DC) and
16 digital channels.

Note 1: The last two fields related to the binary inputs are configure according to the
physical order of the inputs in the back of the RA33x, as in Figure 8: Rear view of the
RA332. The last field corresponds to the inputs 201 to 216 and the next to the last to
217 to 232. In the Part Number the binary fields are inverted in comparison with the
physical order.
Note 2: The analog board options 2 and 6 are only available from RPV311 firmware
version 14 onwards.

50 RPV311-TM-EN-13.1A
RPV311 Chapter 4 – Configuration

C The Fiber length text field allows user to enter the fiber length, in meters, to compensate the delay in the
data transmission between the acquisition and processing modules.

All analog channels have two configuration options. Circuits and channels will be configured based on the option selected.
In the Inputs section, shown in Figure 14, it is possible to configure the analog inputs of the acquisition module connected
with the RPV311 configured in the previous section. It is important to configure the analog inputs for voltage or current,
according to the physical configuration of the module, shown in Chapter 15: Installation. The RA333's high-speed acquisition
channels do not require configuration, since they are dedicated for voltage measurement.
To improve the accuracy of the measurement, a correction factor can be manually provided. Inputs without the correction
factor have accuracy better than 1%.
The digital channels do not have type selection.

Figure 14: Analog inputs configuration section

A The POSITION indicates the position of each analog input on the back panel of the module.

B The INPUT scroll box allows user to select the type of the signal to be measured (AC voltage 115 V, AC current
1 A, AC current 5 A, DC current 0-20 mA or DC voltage ±10 V).

C The ADJUSTMENT text field allows user to enter a correction factor to adjust the accuracy of the measurement.

RPV311-TM-EN-13.1A 51
Chapter 4 – Configuration RPV311

2.5 Acquisition with Sampled Values

The RPV311 data acquisition can be performed by Sampled Values data, incoming of Merging Units. The acquisition is done
by connecting the Process Bus Ethernet port to the Sampled Values generator.
If the acquisition is done by Sampled Values, there is no physical link to configure. The configuration is performed by
Subscription links. Each subscription link contains data of 4 current (Phases A, B, C and Neutral) and 4 voltage (Phases A, B, C
and Neutral) circuits.
Once a subscription link is created, the RPV311 automatically configures the first channels as current and the last as voltage,
as shown in Figure 16. This is done because the Merging Units send the Sampled Values package according to the IEC 61850-
9-2LE.
The RPV311 processing module can be configured with up to 8* Subscription links.
To configure the links, access the Sampled values subscriptions section, shown in Figure 15.

Figure 15: Sampled Values subscriptions links configuration section

A The ENABLED check box allows user to enable the Subscription link feature.

B The SAMPLED VALUE IDENTIFIER text field allow user to insert the monitored Sampled Values identification.

C The MAC ADDRESS text field allow user to insert the monitored Merging Unit MAC Address.

D The APP ID text field allow user to insert the monitored Sampled Values APP ID.

E The VLAN ID text field allow user to insert the VLAN ID of the monitored Sampled Values.

F The VLAN PRIORITY scroll box allow user to select the priority of the Sampled Values data at the configured
VLAN.

52 RPV311-TM-EN-13.1A
RPV311 Chapter 4 – Configuration

G The SAMPLE RATE scroll box allow user to select the Sampled Values sample rate. 80 points-per-cycle is used for
protection purposes and 256 points-per-cycles is used for measurement purposes.

H The PACKET LOSS TOLERANCE allow user to insert a package-loss rule.

Note 1: The maximum number of Sampled Values streams must be 4. If more

functionalities such as, TW records (RA333), harmonics, flicker and continuous
recording are enabled, this number must respect the equipment processing conditions,
consult the technical assistance for specific cases.

Note 2: in versions from FW15A00 onwards the RPV311 discards any sampled value in
simulated mode. It was changed to avoid receiving the same SV stream in simulated
and non-simulated mode.

In the Inputs section, shown in Figure 16, it is possible to configure the analog inputs of the Sampled Values configured in
the previous section. It is important to configure the analog inputs for voltage or current, according to the Sampled Values
messages received of the monitored Merging Unit.

Figure 16: Analog inputs configuration section for Sampled Values channels
A The POSITION indicates the position of each analog input according to the Sampled Value message.

B The INPUT scroll box allows user to select the type of the signal to be received as Sampled Values.

2.9 Auto Upload

2.9.1 Records
It is possible to send a record to two different servers. In the configuration interface it is possible to configure the IP address
of each destination server and the type of record which will be sent. When a new record is generated and the record type is
enabled for auto upload, it is automatically transmitted to the servers.
If at the upload time the server is not available or the network is unreadable, the record is not retransmitted. In this case,
the record will be transmitted only through the automatic scanning by the server.
The automatic upload of records is a process in which the records are transferred to the server in advance. To ensure that all
the records are stored in the server, it is necessary that the server perform the scanning process periodically. The records
that have already been transmitted to the server are not retransmitted.
In the section shown in Figure 21, it is possible to automatically upload records to a preset destination.

Figure 21: Auto upload configuration section

A The DESTINATION check box allows user to select a record destination IP address previously entered.

4.1 GIC Configuration (Geomagnetically Induced Current)

GICs are quasi-DC currents that cannot be measured with conventional CTs. In conjunction with optical CT and IEC 61850-9-
2LE Merging Units, the RPV311 can be applied to monitored GIC currents in the power system.

To create a circuit to monitor GIC, check the GIC check box in the current circuit wiring screen, as below:

Figure 25: screen used to enable GIC.

This check box configuration will disable the autozero filter that all the RPV311 channels have (autozero is slow filter that
removes the DC components from the measurement) and apply a low-pass first order filter to the current measurement.
This channel will only monitor and show DC measurement then, instead of RMS.
The first order filter has a configurable time constant ranging from 0,1 to 1000 seconds that can be chosen in the last screen
of the current circuit configuration, as below.

Figure 26:screen used to enable GIC.

Note:
In a GIC circuit, the RMS measurement is replaced by the DC measurement. When
creating a threshold in a GIC circuit, the ABC threshold is related to the DC
measurement.

17 PMU
Synchrophasors are measured and broadcast according to the specifications contained in IEEE C37.118, Standard for
Synchrophasors for Power Systems.
For further information about the PMU, see Chapter 8: PMU.
The RPV311 is able to send up to 4 PMU in the frame of data and the configuration is divided into three sub menus: General,
Data and Communication described below.

17.1 General
This window is responsible for configuring the following settings:

<Enable> Turns the PMU streaming on and off.

The <ID> text field allows user to enter a single ID for the entire PMU streaming; the range is of 1 to 65534.
The <Rate> scroll box allows user to select a frame transmission rate; at 60Hz the parameters are10, 12, 15, 20, 30, and 60
fps; at 50Hz they are 10, 25 and 50Hz.

Figure 46: PMU general configuration screen

17.2 Data
The data selection is related to the groups configuration (refer to Chapter 4: Configuration, Section 15 - Groups). Each group
can configure a PMU with its specific data and frequency.
The parameters present on the screen are:
<GROUP> this setting displays all the values related to the selected group that can be transmitted. Each group has a particular
setting for the frequency and rate of change of frequency related to it.
The <ENABLE> check box allows user to enable data packet transmission.
The <ID> text field allows user to enter a single PMU transmitter ID; the range is of 1 to 65534.
<FREQUENCY> selects the reference frequency of PMU. It is possible to choose which signal is used to calculate the frequency,
namely: Voltage from phases A, B or C, voltage positive sequence, current from phases A, B or C.
The <PHASORS>, Analog data and Digital data fields contain all the inputs configured on the equipment. The check box allows
user to select the input to evaluate magnitudes.
The <DESELECT ALL> button allows user to deselect all the magnitudes selected.

Chapter 4 – Configuration RPV311

Figure 47: PMU data configuration screen

17.3 Communication
The RPV311 has two types of operation modes: Commanded; and Spontaneous.
When using the Commanded mode the RPV only transmits data when the client requests. This mode allows up to 4
destinations of the PMU frame through the UDP ports.
The ports the RPV311 uses to send synchrophasors are:

Stream of data Port number

1 4713
2 4714
3 4715
4 4716

In Spontaneous mode the RPV sends the PMU data automatically up to 4 different socket addresses (IP + port number). All 4
destination configuration can be set as unicast or multicast transmission.
The parameters of the Communication screen are listed below:
<COMMANDED> Sets the respective streams of data to Commanded mode. When set to Commanded mode. The RPV311 can
send the HDR, CFG2 and CFG3 frames according to the client’s IED request.
<SPONTANEOUS> Sets the respective streams of data to Spontaneous mode. When in Spontaneous mode it is also possible to
select which CFG frame the PMU will use. The options are CFG2 and CFG3, at least one of them must be set. Additionally, it
is possible to choose if the HDR frame will be sent.
<UNICAST> Sets the addressing of the respective streams of data to Unicast mode. This kind of transmission connects to a
single IP address and the routing of the messages though the available Ethernet ports are managed by the RPV system. It is
important that the destination IP and the RPV311 share the same subnetwork address.
<MULTICAST> Sets the addressing of the respective streams of data to Multicast mode. This mode required the user to choose
which Ethernet interface the RPV shall use to convey the data.

84 RPV311-TM-EN-13.1A
RPV311 Chapter 4 – Configuration

Figure 48: PMU communication configuration screen

Note 1:
When the PMU is configured in spontaneous mode, the RPV311 will transmit the
PMU data through the Ethernet port whose IP address is within the same subnet as
the destination IP address of the PMU stream. In case different streams are
configured, they will be transmitted simultaneously through both Ethernet ports 1
and 2, in case, the subnets of the destination IP addresses match the configured IP
of the RPV311 Ethernet ports.
When the PMU is configured in commanded mode, the RPV311 will transmit the
PMU data through the same Ethernet port as the PMU requisition was made.
Note 2:
When the primary values being read are less then 1A or 1 V, the PMU TVE will not
work properly, i.e. in performance test scenarios do not use transformer ratios
equal to 1.

18 MODBUS
Status, analog and digital data are available in MODBUS registers.
Access to SCADA integration is provided over the Ethernet interface. Up to 8 simultaneous connections are allowed a
maximum rate of 60 accesses per second.
For further information about MODBUS, see Chapter 9: MODBUS.
Each register reports 16-bit data. Registers are divided into 3 groups:

Registers groups
0 Status
100 to 199 Analog data
200 to 223 Digital channels

RPV311-TM-EN-13.1A 85
Chapter 4 – Configuration RPV311

In the MODBUS section shown in Figure 49, it is possible to configure MODBUS.

Figure 49: MODBUS configuration section

A The ENABLE check box allows user to enable recording.

B The ANALOG DATA field allows user to select a derived quantity and insert a decimal correction factor of an
analog input.

C The DIGITAL DATA field allows user to select a block of a digital input.

D The <DESELECT ALL> button allows user to deselect all the magnitudes selected.

Note: Whenever MODBUS/DNP3 feature is enabled, the RPV will send both types of
messages. It is not possible to enable just one protocol.

19 DNP3
The DNP3 functionality is fully associated with the MODBUS functionality in the RPV311. To use the DNP3 protocol, it is
necessary to insert a configuration key at the equipment to unlock the MODBUS and DNP3 functionalities. However, it is
necessary to check the HABILITATED option at the RPV311 Configurator and insert analog channels block or digital channel
blocks at MODBUS/DNP3 menu.

19.1 Configuring the DNP3 function

To add binary data to the DNP3 slave database (RPV311), it’s just necessary to add a digital channel in the equipment’s
configuration, as shown at section 6. At the RPV311 restarting process, the DNP3 library reads the configuration archive and
adds digital channels sequentially, associating to an integer number plus an increment, starting at zero, for each digital
channel. GOOSE digital channels are not added to the DNP3 database.

19.2 DNP3 configuration example

19.2.1 Adding digital channels
First step for digital channel DNP3 database association is to create a digital channel. Figure 50 shows the digital channels
configured and the last column shows associated number at the DNP3 database for each digital channel of the example. The
numbers are related to sequence creation and position in XML configuration file.

Chapter 4 – Configuration RPV311

19.2.2 Adding analog channels

The analog data possibilities for the DNP3 communication protocol are the same as for MODBUS. The MODBUS analog data
are shown in section 1.3.
To configure the analog data, access the MODBUS/DNP3 menu via RPV311 Configurator. Analog data are added in a
sequential way, like the digital channels, but the starting number for the analog channels is 5. Numbers 0, 1, 2, 3 and 4 are
reserved for equipment information.

Note:
For analog channels, the first number associated at the DNP3
database is 5. Numbers 1, 2, 3 and 4 are reserved for equipment
information.

Figure 51 shows the analog channels selected at the MODBUS/DNP3 menu and the table below it shows the associated
number at the DNP3 database for each example analog channel.

2.7 Monitoring
With the monitoring screen in the RPV311 Configurator it is possible to monitor the values related to circuits and channels in
three different ways: through Plots, Current and Voltage Circuits, and Digital Channels.

2.7.1 Measurements
• Voltage and Current Measurement:
The values listed below are computed at the nominal system frequency (50 or 60 Hz):

Voltage and current measurement

ABC RMS value ²
N RMS value (neutral) ²
ABC1 Phasors ¹
N1 Phasors (neutral) ¹
+
S Positive sequence ¹ ²
S− Negative sequence ¹ ²
U Imbalance ¹ ²
F Fundamental frequency ²
THD Total harmonic distortion ²

¹ Is not calculated for circuits of 1 element without 3-phase synthesis.

² Is not calculated for neutral circuits.

The fundamental frequency of the input signal must be within a range of ± 6 Hz of the nominal frequency of the electrical
system.
•
Power Measurement:
Power measurement is computed based on the values of a voltage circuit and a current circuit. The following values are
computed once per cycle:

Voltage and current measurement

S Combined apparent power
S1 Fundamental apparent power
P1 Phasors ¹
Q1 Phasors (neutral) ¹

Reactive power has a positive sign for circuits with inductive characteristics and a negative sign for circuits with capacitive
characteristics.
• DC Transducers Measurement:
The average value of the DC channels (transducers) is calculated once per cycle.
• High-speed Voltage Measurement:
There is an 8-bit opto-isolated analog-to-digital converter, independent for each channel. The acquisition is performed with
5 MHz sampling frequency (high-speed channels), that means one acquisition each 200 ns.

2.7.3 V & I Circuits

The user will be able to monitor the values of voltage and current circuits.
In this interface, up to 4 channels of voltage or current can be simultaneously monitored, as shown in Figure 72.

Figure 72: Monitoring circuit quantities through phasors

A Phasor angle for each phase of the selected circuit.

B Selected circuit to be monitored.

C Quantities related to the circuits being monitored.

Phasor angles measured and displayed are absolute angles referenced to the PPS signal provided by the synchronization.
When no sync signal is connected, the measured angles are referenced to Phase A of the reference circuit.
Values are updated at the rate of 2 points per second, however, when two or more circuits are simultaneously displayed,
their time stamps may not be related to each other.

Note: The RPV311 has an autozero automatic feature, which is a slow filter that
takes about 15 minutes to filter the DC components of the reading signal and then
subtracts it from the readings in order to locate the correct position of the signal
reference on the graph. The response of the filter is stored in the solid memory with
the purpose of turning this process faster for subsequent reboots on the device.
This filter will not interfere with the registering of the DC components generated by
faults. This filter can be disabled in Equipment → Acquisition → Autozero.

3 COMTRADE files download

There are three different ways to get the COMTRADE files from the RPV311 to a computer, one manual way and two
automatic way.
The manual method uses the RPV311 Configurator and is described in the item Chapter 5: Operation, 1.3.3 Records
The two ways automatic ways listed below:
▪ DR Manager (Chapter 13: Software – DR Manager): Elaborate software that downloads the records from several
separate RPVs, performs TW fault location and shows the equipment alarms.
▪ Auto-upload which is a feature of the RPV where the user specifies an IP address and prepare a computer to be
the server. Upon creating a record the RPV will automatically send it to the destination IP. If for some reason, it
is not able to send the record at that time it will not send again later.
All those means save the record to a folder named based on the DFR’s information LOCATION,IDENTIFIER within another
folder located in C:\RPV\records\.

Note: The scanner application was disable after FW15A00.

RPV311-TM-EN-13.1A 117
RPV311
Distributed Multifunction Fault Recorder
Chapter 6: Records
This chapter details all types of registers created by the RPV311.

1 Continuous and Triggered Fault Records

Fault records can be created in the following ways:
• Continuously:
Measurements are continuously recorded. A new record is available every 10 minutes. The record size depends on the
number of derived measurements selected by the user. Up to 16 measurements can be selected. The continuous fault
records does not contain the digital inputs status.
• By trigger:
The fault recorder can be triggered by a Boolean equation, by a cross-trigger signal of another recorder or by a manual
trigger using the RPV311 Configurator.
Continuous and triggered fault records share the same mass storage area.

1.1 Recorded Values

The following values are recorded by the fault recorder:
• Voltage waveform of all voltage circuits (A, B, C, and N);
• Current waveform of all current circuits (A, B, C, and N);
• Transducer waveform of all transducer channels;
• Digital channels (state of digital inputs and binary GOOSE messages – digital
inputs are recorded only in the triggered fault records).

1.2 Recording Times by Trigger

Once triggered, the following parameters are considered by the fault recorder:

Parameter Allowed values Increment

Pre-fault time (𝑡pre ) 0…5s 0.1 s
Post-fault time (𝑡pos ) 0 … 60 s 0.1 s
Timeout 1 … 60 s 0.1 s

The Timeout configures the maximum duration that the actual fault (threshold exceeded/trigger ON) can reach within a
record. The maximum timeout of the fault record is 60 seconds.
The maximum time of the recorded will be composed of the pre-fault time plus fault duration plus post-fault time.

118 RPV311-TM-EN-13.1A
RPV311 Chapter 6 – Records

1.3 Sampling Rate

The trigger recorder sampling rate is user-selectable from 256, 128, or 64 points-per-cycle of the nominal frequency of the
input signal. The size of the records is proportionally affected.
The continuous recorder sampling rate is 16 points-per-cycle of the nominal frequency of the input signal.
Both analog and digital inputs are recorded at the same sampling rate depending on the type of recorder, i.e. Triggered fault
records: 256, 128, or 64ppc and Continuous fault record: 16ppc.

1.4 Re-trigger and Record Concatenation

When two or more consecutive triggers happen, case the post-fault time of the first trigger and the pre-fault time of the
second trigger cross each other, then the RPV311 concatenates both records and stores it in a single COMTRADE file.
In the figure below, if the time T≤ pre-fault time + post-fault time, then the records are concatenated:

Figure 77: Concatenation event example

If the pre-fault time of the second register does not overlap the post-fault time of the first records, then the RPV311 creates
two separate COMTRADE files.
In the figure below, if T ≥ pre-fault time + post-fault time, then the RPV311 creates two separate COMTRADE files.

Figure 78: Example of an event without concatenation

RPV311-TM-EN-13.1A 119
Chapter 6 – Records RPV311

1.5 Trigger Burst Limiter

There is an user-configurable trigger burst limiter for the fault recorder.
The burst limiter is based on the number of triggers time interval (both parameters are user-configurable). When the limit is
exceeded, recording will be disabled for a period of time defined by the user.

Parameter Allowed values Increment

Number of triggers 0 … 12 1
Time interval 0 … 60 s 1s
Disabling time 1 … 60 min 1 min

2 Continuous and Trigger'd Disturbance Records

Disturbance records can be created in the following ways:
•
Continuously:
Derived measurements are continuously recorded. A new record is created at each hour rollover. The record size depends
on the number of derived measurements selected by the user (limited to 64).
• By trigger:
The disturbance recorder can be triggered by a Boolean equation, by a cross-trigger signal of another recorder, by a manual
trigger using the RPV311 Configurator, or by the triggering of the fault recorder. It is possible to select the derived quantity
of triggered disturbance records. If the quantities are not manually selected, the record will consist of all the quantities
available for measurement. The record size depends of the number of derived measurements selected by the user.
Continuous and triggered disturbance records share the same mass storage area.

2.1 Recorded Values

The following values are recorded by the continuous and triggered disturbance recorders:
• RMS value of voltage and current circuits;
• Voltage and current phasors;
• Frequency of voltage circuits;
• Positive sequence of voltage and current circuits;
• Negative sequence of voltage and current circuits;
• Imbalance of voltage and current circuits;
• Total harmonic distortion of voltage and current circuits;
• Apparent combined power of power circuits;
• Apparent fundamental power of power circuits;
• Active fundamental power of power circuits;
• Reactive fundamental power of power circuits;
• Digital channels (state of digital inputs and binary GOOSE messages).

120 RPV311-TM-EN-13.1A
RPV311 Chapter 6 – Records

2.2 Recording Times by Trigger

Once triggered, the following parameters are considered by the disturbance recorder:

Parameter Allowed values Increment

Pre-fault time (𝑡pre ) 0 … 2 min 0.1 min
Post-fault time (𝑡pos ) 0 … 20 min 0.1 min
Timeout 1 … 20 min 0.1 min
The Timeout configures the maximum duration that the actual fault (threshold exceeded/trigger ON) can reach within a
record. The maximum timeout of the disturbance record is 20 minutes.

2.3 Sampling Rate

The trigger and continuous recorder sampling rate is one-per-cycle.
Both analog and digital inputs are recorded at the same sampling rate depending on the type of recorder.

2.4 Re-trigger and Record Concatenation

Two records will be concatenated if the disturbance recorder is re-triggered and there is an overlap between the post-fault
time of the first record and the pre-fault time of the second record.

2.5 Trigger Burst Limiter

There is an user-configurable trigger burst limiter for the disturbance recorder which is identical to the fault recorder limiter.

3 Traveling Wave Fault Records

Faults in a transmission line cause transients traveling along the line as waves composed of by a frequencies ranging of a few
kilohertz to several megahertz.
These traveling waves have a wave front with a very fast rise time and a down time which is relatively slow. The waves move
at speeds near that of light, away of the fault point toward the end points of the line.
The waves are not limited to the transmission line where the fault occurred, spreading through the adjacent electrical
system with decreasing amplitude, the result of the combined effects of the impedance of the line and successive
reflections.
Fault location by traveling waves is based on accurate determination of the moment that the wave fronts pass the two
terminals of the line. The traveling wave recorder can be triggered by a Boolean equation.

3.1 Pre-conditions
The traveling wave fault location requires that a second equipment with the same functionality is installed at the other end
of the monitored power line.
Both units must be synchronized by an IRIG-B signal with less than 100 ns jitter.
Specific traveling wave fault location software must be installed in the user´s computer. This software, using the traveling
wave records of both terminal lines and the power line parameters, executes the fault location algorithm and shows the
fault location estimation. For details about the Traveling Waves Fault Locator software, please refer to Chapter 12: Software
– RPV Tools and Chapter 13: Software – DR Manager.

RPV311-TM-EN-13.1A 121
Chapter 6 – Records RPV311

3.2 Sampling Rate and Acquisition

The acquisition module RA333 has 3 independent channels (one circuit A, B, C), with an 8-bit A/D converter. The sampling
frequency acquisition is 5 MHz, synchronized by a PPS signal, which means one acquisition each 200 ns.
The acquisition module conditions the line voltage signal. With an efficient band-pass filter, the passing frequency is limited
between 1 kHz and 1 MHz.
The module constantly acquires signals and storing the measured values locally in a 64 MB RAM (approximately 4 seconds).
The data is written into a circular buffer where the oldest data will be overwritten by the latest until a threshold violation
occurs.
On detecting violation of the threshold, the memory writing is interrupted. The memorized data is sent to the processing
module at this moment. The complete transfer of data takes about 2 minutes, and in this time the BUSY indicators are lit.
While data is being transferred to the processing module (2 minutes), new TW records will not be registered. During this
time, the other acquisition and processing modules continue functioning normally.

3.3 Recording Times

The recording parameters are fixed and the record has 3 electrical cycles (50 or 60 Hz) before the violation of the limit and
one cycle after, approximately 67 ms at 60Hz and 80 ms at 50 Hz. The duration of recording may vary slightly but this does
not cause in implications for fault location.

4 Steady-State Records
Steady-state records are composed of the following records and measurements:
• Average Series;
• Harmonics;
•
Flicker.
One separate record for each measurement above are created once per day and recorded at 1 ppc.

4.1 Average Series

The equipment continuously records averaged values of

The aggregation time interval is user-selectable between 1 minute or 10 minutes, synchronized to UTC minute rollover. The
timestamp refers to the end of the averaging window.

122 RPV311-TM-EN-13.1A
RPV311 Chapter 6 – Records

4.2 Harmonics
Harmonics are computed for phases A, B and C and for the neutral of up to two voltage or current circuits. The algorithm
used conforms to IEC 61000-4-7:1991.
𝑇𝑤
The signal is band-limited by Hanning-windows with width 𝑇𝑤 = 200 ms, overlapped every = 100 ms.
2
A Fourier transform is used to obtain all frequency components of the input signal up to the 50 𝑡ℎ order.
The values obtained at every measuring window are aggregated over 𝑇vs = 3 s.
Values resulting of the 𝑇vs = 3 s aggregation are aggregated a second time over 𝑇sh = 10 min using classifiers. The result is
the cumulative probability for each harmonic component of the input signal.
For each harmonic component of the input signal, the value that does not exceed the 𝑝 = 1, 10, 50, 90, 95, and 99 %
percentiles in the 𝑇sh time interval is recorded.

4.3 Flicker
Flicker is computed for phases A, B, and C for up to six voltage circuits. The algorithm used conforms to IEC 61000-4-
15:1997+A1:2003.
The aggregation time interval is 10 minutes in the Pst Flicker or Plt Flicker 2 hours, synchronized to UTC minute rollover. The
timestamp refers to the end of the averaging window.

5 SOE - Sequence of Events Records

All variations of the equipment inputs occurred are recorded on this record.
The events in the SOE are recorded with accuracy better than 100µs.
One SOE file is created per day.

6 Record Format and Naming, and Mass Storage Capacity

Chapter 7: TW Fault Locator
This chapter provides information regarding the architecture and the proper use of the Reason Traveling Wave Fault
Location.

1 TWFL Overview
The figure below shows an overview of the Traveling Wave Fault Location architecture.

Figure 79: TW Fault Locator architecture overview

Each terminal of the line must have a set of RPV311 processing unit+RA333 acquisition unit; and each RPV311 must be
synchronized with a GPS Clock as accurate as possible. The signal used to extract the traveling waves if the voltage signal
from the secondary circuitry of the VT.
During a fault the RPV311 in each terminal will register the waveform of the traveling wave in a COMTRADE file, after being
triggered by any of the thresholds described in Chapter 4 - Thresholds.
The DR Manager software will download the COMTRADE files with the TW capture automatically and periodically from all
the RPV311 within the ethernet network and will calculate the distance to fault automatically. More information on the DR
Manager is found in Chapter 13: Software – DR Manager or in the DR Manager user manual.
Chapter 9 – TW Fault Locator RPV311

The RPV from one terminal does not need to communicate with the other terminal’s RPV in order to create the TW
COMTRADE file.
A communication link is only needed between the control centers and the RPVs (or local data concentrators) the user wants
to implement remote access to the equipment.
The communication setup that the user would deploy to download the TW record and perform the fault location is exactly
the same as the one used to download the fault records.
The fault distance is calculated based on the time that each wavefront arrived at the line terminal. According to the
following equation.
𝑙 + 𝐾𝑐(𝑡𝑎 − 𝑡𝑏 )
𝑑 =
2
Where:
d: fault distance from terminal A;
l: length of the line;
k: constant of the line attenuation of the speed of the wave;
c: speed of light
ta: time which the traveling wave gets to terminal A
tb: time which the traveling wave gets to terminal B
The means to get the COMTRADE files from the RPV311 to the computer where the fault location will be performed are
described in Chapter 5: Operation, COMTRADE files download.

2 TW Fault Location Information

2.1 TW Triggering System

The TW record is a COMTRADE file with 3 cycles prior to the trigger plus 1 cycle after the trigger, that means approximately
67 ms @ 60 Hz and 80 ms @ 50 Hz. The RPV311 takes about 30 seconds to create a record and it can create up to 4 records
at the same time. When 4 records are being created at the same time new triggers will not create a record and the “BUSY”
LED in the RA333 will turn on. After the record from the first trigger is finished, then the RA333 will be able to capture the
next trigger.
Trigger events that happen within a time window of 1 electric cycle will create a single TW COMTRADE file. If another trigger
happens after 1 cycle from the first trigger of the event, then another TW COMTRADE file will be created.

2.1.1 Consecutive Faults

The RPV311 can have up to 4 TW COMTRADE files being created at the same time, it means that it can record and locate
faults in at least 4 consecutive events in a 2-minute time frame, such as evolving faults and switch-on to fault operations

Note:
For regular 3-phase circuits, the triggers are also 3-phase, i.e. in an event where a
fault evolve to another phase, the trigger will already be sensitized by the previous
fault. Since the TW recorder do not have a retrigger system it is necessary that a
new trigger activates for the TW recorder to capture the consecutive event. To do
so, it is necessary to have binary triggers monitoring the different protection trips
that will detected the consecutive events, by doing so only the phase involved in
each fault will trigger at a time, allowing the multiple recordings.

128 RPV311-TM-EN-13.1A
RPV311 Chapter 9 – TW Fault Locator

2.2 Switch-on to Fault

When a short circuit occurs right after the circuit breaker closes, the behavior of the traveling waves become different from
regular faults, mainly because the circuit breaker itself can create traveling waves that can be misinterpreted as traveling
wave from the fault and it may turn the fault location calculation more difficult. To avoid that, the DR Manager analyses
both the waveform/fault and the TW COMTRADE records to first identify that a switch-on event occurred and then to apply
a special fault location algorithm. Additionally, special conditions need to be met for the switch-on to fault (SOTF) events to
be located automatically:
▪ The fault shall be at least 6 km away from both line terminals.
▪ The transmission line maximum length shall be 2000 km.
▪ The fault location for switch-on events will not work for mixed (hybrid) lines.
▪ There needs to be a corresponding waveform recording for each event
(Chapter 4: Configuration. 10. Fault Recorder).
Even meeting all the conditions above, SOTF events are rare and difficult to interpret automatically, thus, the DR Manager
will indicate on its interface whenever an event is characterized as a switch-on so the user can be cautious and double check
the recordings.

2.3 Maximum Number of Lines Monitored by the TW Fault Locator

If the voltage is sourced from a bus VT you only need one RA333 to capture TWs from all the lines connected to that bus.
Moreover, it is possible to connect up to 4 modules RA333 to one processing unit RPV311.

2.4 Underground and Overhead Cables

There are no restraints regarding the fact that the cable is underground. In the calculation of the fault location, there is a
parameter k (as presented in the fault location formula aforementioned) that depends on the physical characteristics of the
wire. When the TW fault locator method is used on combination of cable. The user can configure the TW fault location in
two manners: using the mixed lines configuration, where the user will configure a different k parameters for each section of
the line. This method does not lose accuracy; or use a single average k for the entire line. , note that the average k will not
represent the actual k of the line at the faults location. It is an approximation, therefore it will present less accuracy.

Note:
The maximum number of RA333 that can be connected to the RPV311 is 4.

The RA333 module has to be connected to the RPV311 processing module before
its initialization. Otherwise a log message will tell the user to reboot the device.

3 Automatic Fault Location

The DR Manager software is a tool design for management of COMTRADE files, configuration and fault location. One of its
features is the automatic TW fault location.
The DR Manager download the COMTRADE files from both terminals of the line, performs the fault location calculations,
displays the fault location results in its interface and sends the location via MODBUS to the supervisory system.
Details on the configuration procedure, please refer to Chapter Software – DR Manager.

Chapter 9 – TW Fault Locator RPV311

4 How to Test the TW Fault Location in Lab

The most complete test would be using two sets of RPV311+RA333:
1. Make sure that both RPV311 are properly time synced. For conditions that are
more realistic, the sync sources could be independent;
2. Configure a line arbitrarily long on the DR Manager or TW Fault Locator
software connecting the two sets of equipment;
3. Configure the TW register to be triggered by an undervoltage threshold in
both RPV311;
4. Connect three phase voltage to the TW analogic inputs in both RPV311 though
a circuit-breaker or test switch;
5. Switch off the circuit-breaker (or test switch), both RA333 should indicate the
BUSY state, showing that the TW is being processed. register is being
processed;
6. Download both files to a computer with the TW Fault Locator tool installed.
7. Run the TW Fault Locator tool to find the fault location (Procedure described
RPV311 manual, in topic 14.5). The fault location should be 50% of the line.
Alternatively, it is possible to useone RPV311 and two RA333 connected to the same RPV311. Taking care when creating the
powerline file, in which only the “line” parameter will be different, for example:
<terminal_a>LOCATION,IDENTIFIER,LINE_A</terminal_a>
<terminal_b>LOCATION,IDENTIFIER,LINE_B</terminal_b>
Another possibility that also tests the acquisition system of the RA333 module, is to use only one RPV311+RA333 and
configure the powerline file with the same parameters for both terminals, for example:
<terminal_a>LOCATION,IDENTIFIER,LINE_A</terminal_a>
<terminal_b>LOCATION,IDENTIFIER,LINE_A</terminal_b>
In this case, the TW fault locator tool will use the same file for both ends locating the fault.
For all the previous mentioned tests, the algorithm shall point the fault location at 50% of the line length, as we are using
with very short cable lengths or using the same TW register for both ends.

5 Three Terminal Line Application

The figure below shows a line of three-terminal. The Terminal A, B and C (sources X, Y and Z respectively).

Figure 80: Typical Circuit Three-Terminal Application

RPV311 Chapter 9 – TW Fault Locator

To use TWFL in the case above 3 sets of equipment are necessary: 3(RPV311 + RA333). One set for each terminal (Figure
81).
In this application, it is necessary to configure two transmission lines in the TW Fault Locator tool, which means to create
two powerline configuration files. The first powerline configuration file is regarding line A -> B with length and k1 equal to L1
= L1’ + L1’’ (Figure 81), and the second powerline file configuration regarding the section C -> B with length and k1 equal L1’’
+ L2 (Figure 81).
In order to locate the fault is necessary to combine the fault location of both situations describe above.

Figure 81: Three terminal line application

5.1 Examples
Consider the TAP point located at 50% of line A-B and 50% of line C-B. Consider the names and topology of Figure 81.
Example 1:
If the result of the fault location of the line A-B returns more than 50% of the length of the line and the result of the fault
location of line C-B also returns more the 50% of the length, then we know the fault is in the L1’’ section, as in Figure 81
Figure 82.
Example 2
Now consider the result of fault location on line A-B being at more than 50% of the length and the result of the fault location
on line C-B at less than 50%, then we know the fault is in the L2 section, as in Figure 82 and Figure 83 show the location of
the faults in example 1 and 2, respectively.

6 TWFL in Mixed (Hybrid) Lines

A hybrid transmission line is comprised of two or more different line types. That matters for the TWFL because the velocity
of the fault wave is different in each section of the line and that shall be taken into account during the fault distance
calculations.
The wave velocity is related to the relative permittivity of the main insulation and different thicknesses of the semi-
conducting layers. Assuming one constant wave velocity for such a line will result in errors.

6.1 K Factor Calculation – Overhead Section

In the case of K factor relating to overhead line, without insulating material, it is considered that the dielectric material
insulating the cable is only the air. In this case, the constant of permeability and permittivity is very close to 1.0.

𝜇𝑟𝑎𝑖𝑟 ≅ 1 𝜖𝑟𝑎𝑖𝑟 ≅ 1

𝐾𝐶
𝑉𝑤𝑎𝑣𝑒𝑜𝑣𝑒𝑟ℎ𝑒𝑎𝑑 = ≅ 1.0𝐶
√𝜇𝑟𝑎𝑖𝑟 𝜖𝑟𝑎𝑖𝑟

In overhead lines, the velocity of the fault wave is very close the speed of light, between 98% and 99.5%, it means that the
factor K ranges from 0.985 to 0.995. Calculating the K precisely is a very complex task, because it depends on unknown

132 RPV311-TM-EN-13.1A
RPV311 Chapter 9 – TW Fault Locator

constants of permeability and permittivity of the overhead cable dielectric, which in this case is the air. That means that
these constants may vary with humidity, atmospheric pressure and distance between the conductors of the transmission
line in question.
Therefore, during commissioning, the K is usually set to 0.99 and improved later based on the data from subsequent fault
location distances.

6.2 K Factor Calculation – Underground Section

In this type of table the insulation material have permeability and permittivity well defined for the entire cable, which makes
it easier to calculate the k factor more accurately.
A common material used in the insulation of these cables is the XLPE. The example below shows the calculation of the K
parameter using XLPE cable and its permeability and permittivity constants, where the result is K = 0.66.

𝜇𝑟𝑥𝑙𝑝𝑒 ≅ 1 𝜖𝑟𝑥𝑙𝑝𝑒 ≅ 2.3

Chapter 11: GOOSE Message Detection
This chapter provides detailed information about the GOOSE message detection functionality.

1 Description
Digital channels can be associated with physical electrical digital inputs or associated to the detection of IEC61850, GOOSE
messages.
GOOSE messages are captured and filtered by one of the Ethernet interfaces installed at the communications module. The
state of the binary variables in the GOOSE message associated with digital channels and can be included in trigger equations,
and can be stored in the fault record, disturbance record, and in the sequence of event (SOE) record.
The equipment can detect up to 320 binary inputs. The dataset types supported are:
• Boolean data type (1 bit);
• Bitstring data type (group of 64 bits);
• Enumeration data type (compare with some value to create a Boolean state).
GOOSE messages can be filtered by VLAN, MAC addresses and by the application identifier.
The association between the GOOSE messages and digital channels is made using the GOOSE Configurator, which is part of
the RPVTools package. For details about the GOOSE Configurator configuration see Chapter 12: Software – RPV Tools.
The RPV311 GOOSE subscription is tested and attested for conformance according to IEC 61850 by DNV GL (KEMA).

Note:
All the three rear Ethernet ports are capable of reading the GOOSE messages, but
the same GOOSE messages shall not be sent to more than one port at the same
time because they will be processed again by the device as it was the same
message causing wrong readings.

1.1 GOOSE Timestamp Behavior

Depending on the following conditions, the RPV311 will chose whether to use the timestamp within the GOOSE message or
the RPV311 own internal clock to position the message in time in the records.
The RPV311 considers two different time quality bits of the GOOSE message (IEC61850-8-1) when deciding the point in time
the message should be positioned. Whenever either the “ClockFailure” or the “Clock not synchronized” are asserted in the
message coming in; or the difference between the GOOSE timestamp and the RPV311 internal clock is larger than 1 electric
cycle, then the RPV311 will disregard the timestamp within the message and use the internal clock as time reference to
record the message.

1.4 TW Fault Locator

1.4.1 Description
The TW Fault Locator is a tool that uses the records of the traveling wave front signals at two ends of a transmission line to
locate a fault in this line.
To record traveling waves in RPV it is necessary to install the appropriate acquisition module, RA333. The records of
traveling waves at both ends of the line should be transferred of RPV's to the specific area of records in the user's computer
that will run the Fault Locator software.
By using a graphic interface, based on the distance between terminals A and B and on the time stamp of the wave front, and
by running the algorithm, the fault can be located. If unable to locate the fault automatically by the software, it is necessary
to use a graphical tool to identify the times of the wave front of each terminal manually. Of the time identified it is possible
run the fault locator graphically. If the locations of the towers between the ends of the line are defined, the results are
georeferenced and a KML file is created for viewing through Google Earth.

1.4.2 The Power Line Configuration

Before running the fault locator algorithm, it is necessary to establish the power line configuration. The basic information
related to the power line must be described in an XML file with the following fields:

Power line file configuration

<length>nnn</length> Nominal length of the line as the owner of the line
claims (in kilometers)
<k1>nnn<k1> Is the coefficient related to the length of the line,
represents the actual length of the cable of the line.
This value can be adjusted using data of faults
subsequent to the commissioning
<k2>nnn<k2> Is the coefficient related to the light speed factor
<terminal_a>Location,Identifier,Line</terminal_a> STATIONID,DEVICEID and the terminal identifier
<terminal_b>Location,Identifier,Line</terminal_b> STATIONID,DEVICEID and the terminal identifier
<tower id=”X” name=”NAME”> Is the identification of the towers and their
<latitude>nnn</latitude> geographic coordinates. This information must be
<longitude>nnn</longitude> provided by the user

<distance>nnn</distance>
</tower>
RPV311-TM-EN-13.1A 149
Chapter 12 – RPV Tools RPV311

The geographic coordinates are optional and must be provided by the user.
The technical note "Traveling Wave Fault Locator (NT0802)" shows how the coefficients K1 and K2 are calculated.

A model of the power line configuration file is created in the directory C:\RPV\faultlocator\conf of Windows after the RPV

record on this list is named with a time stamp. User must select one time stamp of each terminal that matches
the same event. When selecting the record one terminal, it automatically selects a record with the same
timestamp at the other terminal.

The TW Fault Locator Software considers the time zone information in the COMTRADE file’s name, in order to
set the register of both sides of the transmission line at UTC Time for calculations. Therefore, lines that go
beyond two diferent time zones will not canse the algorithm to miscalculate the fault location.

C Selector of sensitivity for the fault location.

COMTRADE registers from both line ends, calculates the fault location, displays it on the software interface and make it
available via Ethernet MODBUS.

2.3.1 Description
After the fault location calculations are performed, the distance to fault is displayed on the software interface and it is made
available via MODBUS communication according to the MODBUS IDs configured on the Transmission Line configuration
menu and the IP address configured in the windows Ethernet properties of the DR Manager computer.
MODBUS Fault Location Transmission
Whenever a TW fault location is performed the DR Manager will provide three separate 16-bit MODBUS registers. The
registers are described below:

Description MODBUS Observation

MODBUS identifier configured on the Transmission Line menu used to identify
Register_1 30001
which transmission line the current fault location refers to.
As the fault location is split into 2x16-bit register. This register carries the LSBs
Register_2 30002
(least significant bits) of the 32-bit register.
Second part of the fault location. This register carries the MSBs (most
Register_3 30003
significant bits) of the 32-bit register.

In order to achieve the actual fault location, it is necessary to combine the 2 fault location registers (30002 and 30003) into a
single 32-bit value. The register 30003 is a decimal representation of the 16 most significant bits of the complete 32-bit
register which contains the fault location and the register 30002 is a decimal representation of the 16 least significant bits of
the 32-bit register. The combination of them will result in the actual fault location in meters.
Below is the necessary operation to combine both fault location registers:
Actual fault location in meters = ((Register_2 & 0XFFFF) | (Register_3 << 16))
When consecutives fault locations are found for the same line, the DR Manager will display all the fault locations as list. And
these locations are going to be sent via MODBUS with a 1-minute time interval between them.

2.3.2 Switch-on to Fault

When a short circuit occurs right after the circuit breaker closes, the behavior of the traveling waves become different from
regular faults, mainly because the circuit breaker itself can create traveling waves that can be misinterpreted as traveling
wave from the fault and it may turn the fault location calculation more difficult. To avoid that, the DR Manager analyses
both the waveform/fault and the TW COMTRADE records to first identify that a switch-on event occurred and then to apply
a special fault location algorithm. Additionally, special conditions need to be met for the switch-on to fault (SOTF) events to
be located automatically:
▪ The fault shall be at least 6 km away from both line terminals.
▪ The transmission line maximum length shall be 2000 km.
▪ The fault location for switch-on events will not work for mixed (hybrid) lines.
▪ There needs to be a corresponding waveform recording for each event
(Chapter 4: Configuration. 10. Fault Recorder).

Even meeting all the conditions above, SOTF events are rare and difficult to interpret automatically, thus, the DR Manager
will indicate on its interface whenever an event is characterized as a switch-on so the user can be cautious and double check
the recordings.

2.3.3 TW Fault Location Methods

The DR Manager uses two calculation methods for TW fault location. They are called “Basic” and “Advanced”. The method
used for each calculation is identified on the DR Manager interface, as shown in Figure 104. The two methods are described
below:
• Basic Method
Uses a threshold configured on the Transmission Line menu, which is a percentage value of the full scale of the register, to
identify the beginning of the traveling wave created by the fault and, consequently, to find its timestamp in order to use in
TWFL calculations. This method uses only the high frequency COMTRADE files acquired by the RA333 units locate the fault.
• Advanced Method
This method uses both the fault register (waveform at 50/60Hz) and the TW register (high frequency register) to identify the
fault location. The fault register is analyzed using a high-pass filter in order to find the time window that contains the fault
begging, then that time window is used in the TW register to enhance the location of the correct time stamp for the fault. As
the time window to track the fault waveform in narrow down using this method, various system noises are eliminated from
the calculations increasing significantly the chances to automatically find the fault.

Chapter 15: Installation
This chapter provides information about the product installation.

1 Handling the Goods

Our products are of robust construction but require careful treatment before installation on site. This section discusses the
requirements for receiving and unpacking the goods, as well as associated considerations regarding product care and
personal safety.

Before lifting or moving the equipment you should be familiar

with the Safety Information chapter of this manual.

1.1 Receipt of the Goods

On receipt, ensure the correct product has been delivered. Unpack the product immediately to ensure there has been no
external damage in transit. If the product has been damaged, make a claim to the transport contractor and notify us
promptly.
For products not intended for immediate installation, repack them in their original delivery packaging.

1.2 Unpacking the Goods

When unpacking and installing the product, take care not to damage any of the parts and make sure that additional
components are not accidentally left in the packing or lost. Do not discard any CDROMs or technical documentation. These
should accompany the unit to its destination substation and put in a dedicated place.
The site should be well lit to aid inspection, clean, dry and reasonably free from dust and excessive vibration. This
particularly applies where installation is being carried out at the same time as construction work.

1.3 Storing the Goods

If the unit is not installed immediately, store it in a place free from dust and moisture in its original packaging. Keep any de-
humidifier bags included in the packing. The de-humidifier crystals lose their efficiency if the bag is exposed to ambient
conditions. Restore the crystals before replacing it in the carton. Ideally regeneration should be carried out in a ventilating,
circulating oven at about 115°C. Bags should be placed on flat racks and spaced to allow circulation around them. The time
taken for regeneration will depend on the size of the bag. If a ventilating, circulating oven is not available, when using an
ordinary oven, open the door on a regular basis to let out the steam given off by the regenerating silica gel.
On subsequent unpacking, make sure that any dust on the carton does not fall inside. Avoid storing in locations of high
humidity. In locations of high humidity, the packaging may become impregnated with moisture and the de-humidifier
crystals will lose their efficiency.

176 RPV311-TM-EN-13.1A
Chapter 15 – Installation RPV311

The device can be stored between -10° to +50°C for unlimited periods, or between -25° to -10 and +50° to +70°C (see
technical specifications).

1.4 Dismantling the Goods

If you need to dismantle the device, always observe standard ESD (Electrostatic Discharge) precautions. The minimum
precautions to be followed are as follows:

10 Connection Between RPV311 and RA331, RA332 or RA333

The RPV311 can process a maximum number of 64 analogue channels that can be achieved using 8 acquisition modules.
The RPV311 processing unit allows connection with up to 8 RA331 acquisition modules, up to 4 RA332 acquisition modules
or up to 4 RA333 acquisition modules respecting the maximum quantity of 64 analog channels. That is: when it is using only
RA332, it is possible to install a maximum of 4 modules with 16 analog inputs each, and when it is using only RA331, it is
possible to install up to 8 modules with 8 analog inputs each. When it is using only RA333, it is possible to install a maximum
of 4 modules with 8 analog and 3 TW inputs each one (each TW board counts as 8 analogue channels). The RA331, RA332,
and RA333 can be connected to the same RPV311 processing module.
Each link on the RPV311, composed of a pair of fiber-optic connectors, is named from A to H. For each link, an optical fibers
pair is used to make transmission and reception of data between the processing module and the acquisition modules.
Connections with acquisition modules must be made according to the sequence of RPV311 identification: the first
connection should be made with link A, the second, with link B, and so forth.
On the RPV311, each link has an ACT indicator, as shown in Figure 115, which lights up when the link is receiving data of the
acquisition module.

Figure 115: RPV311 Fiber Optic Connectors

The RA331 and RA332 modules each occupy one physical link of the processing module. The RA333 occupies two physical
links of the processing module, one for data transmission of analog channels (DFR) and the other for data transmission of
TW channels (TW).
On the RA331, RA332 and RA333 (TW and DFR) modules, each link has an indicator showing the state of the connection with
the processing module, as shown in Figure 116. These indicators, LINK and ACT, on the front panel and back panel,
respectively, light up when the link is active (i.e. it is receiving requests of the processing module).

For information about optical fiber types and link specifications, see Chapter 17: Technical Specifications.
When more than one RA333 module is required, an internal module jumper must be configured, according to the TW link
position. The position of links does not have to be consecutive, but module installation related to A to H position must
match the jumper identification. For example, ID 0 must be the first RA333 (TW) link, ID 1 must be the second RA333 (TW)
link, and so on.
In order to configure these jumpers, remove all connectors and cables which are connected to the module and remove the
back panel of the RA333 removing the 12 screws of the panel and the screw of the protective grounding, as shown in Figure

18 Time Synchronization Inputs

Timing synchronism is provided by the IRIG-B000/001/002/003/004/005/006/007 signal. The IRIG-B signal is used to keep
the RPV311 data acquisition frequency constant and to provide the time stamp for the equipment.
The equipment indicates sync when the data acquisition frequency is according to the equipment's nominal acquisition
frequency and the equipment's internal clock is updated.
The RPV311 internal clock is updated with every hour rollover or when the equipment turns to sync mode.
If the IRIG-B signal is not valid or not connected, the device indicates no sync. If the IRIG-B signal is connected and valid, the
time quality of the time reference reported in the IRIG-B frame is shown by the RPV311, but the time quality is not
considered by the synchronization.
In the absence of the IRIG-B signal, the equipment can be synchronized by an SNTP time server, however, the acquisition
frequency does not have the same stability afforded by the IRIG-B signal (accuracy less than 12 ppm), and the equipment
does not indicate sync.
The IRIG-B signal is preferred over the SNTP time server.
If no IRIG-B signal is available and the SNTP server is unreachable, the unit obtains the time of an internal CMOS clock. Drift
is better than 0.1 second in 24 hours.
The RPV311 has an electrical and an optical IRIG-B input, as shown in Figure 137.

To synchronize the equipment using fiber-optic input, use the appropriate fiber-optic type, considering its minimum
curvature radius.
The use of a twisted pair cable is recommended for the electrical input.

For distances greater than 3m, to minimize EMI effects, the

use of fiber-optic cable is recommended.

Chapter 16: Maintenance and Troubleshooting
This chapter provides information about proper equipment maintenance and troubleshooting.
The troubleshooting part of the chapter allows an error condition on the IED to be identified so that appropriate corrective
action can be taken.

1 Maintenance

1.1 Maintenance Checks

In view of the critical nature of the application, GE Vernova Grid Solutions products should be checked at regular intervals to
confirm they are operating correctly. GE Vernova Grid Solutions products are designed for a life in excess of 20 years.
The devices are self-supervising and so require less maintenance than earlier designs of protection devices. Most problems
will result in an alarm, indicating that remedial action should be taken. However, some periodic tests should be carried out
to ensure that they are functioning correctly and that the external wiring is intact. It is the responsibility of the customer to
define the interval between maintenance periods. If your organization has a Preventative Maintenance Policy, the
recommended product checks should be included in the regular program. Maintenance periods depend on many factors,
such as:
• The operating environment
• The accessibility of the site
• The amount of available manpower
• The importance of the installation in the power system
• The consequences of failure

Although some functionality checks can be performed from a remote location, these are predominantly restricted to
checking that the unit is measuring the applied currents and voltages accurately and checking the circuit breaker
maintenance counters. For this reason, maintenance checks should also be performed locally at the substation.

Before carrying out any work on the equipment you should

be familiar with the contents of the Safety Section and the
ratings on the equipment’s rating label.

The RPV311 has a small coin-battery to power the internal

clock. In order to replace it, please follow the battery
replacement procedures presented in this chapter.

1.1.1 Alarms
First check the alarm status LED to see if any alarm conditions exist. If so, press the Read key repeatedly to step through the
alarms.
After dealing with any problems, clear the alarms. This will clear the relevant LEDs.

203 RPV311-TM-EN-13.1A
RPV311 Chapter 16 – Maintenance and Troubleshooting

1.1.2 Measurement Accuracy

If the power system is energized, the measured values can be compared with known system values to check that they are in
the expected range. If they are within a set range, this indicates that the A/D conversion and the calculations are being
performed correctly.
Alternatively, the measured values can be checked against known values injected into the device using the test block, (if
fitted) or injected directly into the device's terminals.

1.2 Replacing the Unit

If your product should develop a fault while in service, depending on the nature of the fault, the watchdog contacts will
change state and an alarm condition will be flagged. In the case of a fault, you should normally replace the cradle which
slides easily out of the case. This can be done without disturbing the scheme wiring.
In the unlikely event that the problem lies with the wiring and/or terminals, then you must replace the complete device,
rewire and re-commission the device.

If the repair is not performed by an approved service centre,

the warranty will be invalidated.

Before carrying out any work on the equipment, you should

be familiar with the contents of the Safety Information section
of this guide or the Safety Guide SFTY/4LM, as well as the
ratings on the equipment’s rating label. This should ensure
that no damage is caused by incorrect handling of the
electronic components.

Before working at the rear of the unit, isolate

all voltage and current supplying it.

1.3 Cleaning

Before cleaning the device, ensure that all AC

and DC supplies and transformer connections
are isolated, to prevent any chance of an
electric shock while cleaning.

Only clean the equipment with a lint-free cloth dampened with clean water. Do not use detergents, solvents or abrasive
cleaners as they may damage the product's surfaces and leave a conductive residue.

204 RPV311-TM-EN-13.1A
Chapter 16 – Maintenance and Troubleshooting RPV311

1.4 Watchdog
The RPV311 presents an internal watchdog algorithm. This algorithm verifies, every second, if the device’s system is
responding correctly. Case the system does not respond the device performs a hardware reboot while the output relay 1
signals that the RPV311 is off.

1.5 Coin-battery replacement procedure

.

Before carrying out any work on the equipment, you

should be familiar with the contents of the Safety
Information section of this manual, as well as the ratings
on the equipment’s rating label. This should ensure that
no damage is caused by incorrect handling of the
electronic components.

Before working at the rear of the unit, isolate

all voltage and current supplying it.

The RPV311 coin-battery (3V CR2032) supplies energy for the internal clock and mother-board BIOS. Its average life span is 3
years, after which it is advisable to replace the battery.
The user can either ship the device to a GE technical support center or replace it following carefully the procedure described
in this section.
The battery is only accessed using specific tools to open the equipment cabinet and expose the battery.

The battery connector is design to fit only battery with right

size and with correct polarity position. In case, the battery
does not fit, do not force the fitting. Stop and reassess
whether the right battery and right polarity is being
applied.
To replace the battery, follow the procedure below:
1. Disconnect the power supply;
2. Disconnect all other connections leaving the grounding strap to be removed at the end;
3. Perform a visual inspection to make sure the equipment is isolated;
4. Position the device in place where there is free space to work and make sure to install proper working and
safety warnings at the location, also keep available all tools and aids that is going to be used;
5. Wait a few minutes so the capacitors may discharge;
6. Disassemble the device by unscrewing the case screws and pulling up the top side of the case; after that. Keep
in mind that disassembling the equipment may expose sensitive electronic circuitry. Take suitable precautions
against electrostatic voltage discharge (ESD) to avoid damage to the equipment.
7. Locate the CR2032 battery. It has 20mm of diameter and looks like the picture below:

RPV311-TM-EN-13.1A 205
RPV311 Chapter 16 – Maintenance and Troubleshooting

8. Use your fingers to grab on the edge of the battery and pull it up and out of the socket holding it in place.
9. Insert the new battery.

After the replacement, follow the procedure below in order to verify the safe state of the equipment and to put it back into
operation.
1. Reconnect all internal cable that have been removed for the repair;
2. Perform a visual inspection on the device to make sure there are no remainders of the repair service inside the
casing or any other noncompliance;
3. Place back the top side of the case and fasten it using the proper screws;
4. Connect the grounding strap and then the power supply to the equipment;
5. Wait for the equipment to initialize, it will run self-diagnostic routines and if everything is right the “Ready” LED
on its front panel will light up indicating the equipment is safe and operational;

2 RPV311 Troubleshooting

2.1 Ready in processing module does not light up

The unit continuously executes an internal auto-diagnosis routine. The result of this diagnosis is reflected by the Ready led
on the front panel of the unit, on the status page of the monitoring screen and by the failure relay (normally closed contact)
on the back panel of the unit.
If the local interface does not operate, the Ready indicator does not light up. In this case, the processing module must be
sent for technical assistance.

2.2 Alarm LED lights up

If the indicator is lit up, the equipment may have some of the problems described below. To identify the problem that
generated the alarm, access the status of equipment and links in the monitoring screen, as shown in Chapter 5: Operation.

1 Connection Diagrams of the Voltage Inputs

The RPV311 provides the capability for making some different voltage signal connections for a 3-phase circuit:

Connection diagram of the voltage inputs

4-element connection: in this

case, the values shown are
equivalent to the voltages of
phases A, B and C, and to the
neutral voltage applied to the
equipment.

3-element (Phases A, B and C)

connection: in this case, the
fourth element is derived of the
values measured by the other
elements. The three elements
are equivalent to the values
applied to the equipment

3-element (Phases A, B and

neutral) connection: in this
case, the fourth element is
synthesized of the values
measured by the other
elements. The three elements
are equivalent to the values
applied to the equipment.

3-element (Phases A, C and

neutral) connection: in this
case, the fourth element is
derived of the values measured
by the other elements. The
three elements are equivalent
to the values applied to the
equipment.

3-element (Phases B, C and

neutral) connection: in this
case, the fourth element is
derived of the values measured
by the other elements. The
three elements are equivalent
to the values applied to the
equipment.

2-element connection: in this

case, the neutral voltage is
zero, and the three phase-to-
ground voltage are computed
based on the two line-to-line
voltages applied to the
equipment.

In circuits of 1 element, the measurements can be in two different ways:

An isolated phase or neutral measurement: If the element is a phase, only the voltage related to this channel is measured
considering the off-set compensation. If the element is a neutral, the voltage related to this channel is measured without the
off-set compensation.
A 3-Phase synthesis: The magnitude for the 3-phases is considered with the same value as that of the channel measured and
balanced (i.e., angles with 120º between each other).

are equivalent to the
voltages of phases A, B and
C, and to the neutral
voltage applied to the
equipment.

element is derived of the
values measured by the
other elements. The three

3-element (Phases B, C
and neutral) connection:
in this case, the fourth
element is derived of the
values measured by the
other elements. The three
elements are equivalent to
the values applied to the
equipment.

2-element connection: in
this case, the neutral
voltage is zero, and the
three phase-to-ground
voltage are computed
based on the two line-to-
line voltages applied to the
equipment

In circuits of 1 element, the measurements can be in two different ways:

An isolated phase or neutral measurement: If the element is a phase, only the current related to this channel is measured
considering the off-set compensation. If the element is a neutral, the current related to this channel is measured without the
off-set compensation.

A 3-Phase synthesis: The magnitude for the 3-phases is considered with the same value as that of the channel measured and
balanced (i.e., angles with 120º between each other).

1 Equipment Log
The equipment log contains information about:
• Threshold violations, fault and disturbance triggers and data recording;
• Data record transfer (including the IP address to which data has been transferred);
• Access to the unit's configuration pages (including IP address of which the access was performed);
• Alarms and the results of auto-diagnosis routines;
• Power-up and shutdown.

The equipment log cannot be erased by the user. Its capacity is enough for approximately 5 years of typical use, with past
events being erased if memory space is needed.
