Direct connect voltage limits

You can connect the meter’s voltage inputs directly to the phase voltage lines of
the power system if the power system’s line-to-line or line-to-neutral voltages do
not exceed the meter’s direct connect maximum voltage limits.
The meter's voltage measurement inputs are rated by the manufacturer for up to
277 V L-N / 480 V L-L. However, the maximum voltage allowed for direct
connection may be lower, depending on the local electrical codes and regulations.
As per installation category II / III the maximum voltage on the meter voltage
measurement inputs should not exceed 277 V L-N / 480 V L-L for CAT III and 347
V L-N / 600 V L-L for CAT II.
If your system voltage is greater than the specified direct connect maximum
voltage, you must use VTs (voltage transformers) to step down the voltages.

Balanced system considerations

In situations where you are monitoring a balanced 3-phase load, you may choose
to connect only one or two CTs on the phase(s) you want to measure, and then
configure the meter so it calculates the current on the unconnected current
input(s).
NOTE: For a balanced 4-wire Wye system, the meter’s calculations assume
that there is no current flowing through the neutral conductor.

Balanced 3-phase Wye system with 2 CTs

The current for the unconnected current input is calculated so that the vector sum
for all three phases equal zero.

Balanced 3-phase Wye or Delta system with 1CT

The currents for the unconnected current inputs are calculated so that their
magnitude and phase angle are identical and equally distributed, and the vector
sum for all three phase currents equal zero.
NOTE: You must always use 3 CTs for 3-phase 4-wire center-tapped Delta or
center-tapped open Delta systems.

Serial communications
The meter supports serial communications through the RS-485 port. Up to 32
devices can be connected on a single RS-485 bus.
In an RS-485 network, there is one master device, typically an Ethernet to RS-485
gateway. It provides the means for RS-485 communications with multiple slave
devices (for example, meters). For applications that require only one dedicated
computer to communicate with the slave devices, an RS-232 to RS-485 converter
can be used as the master device.

RS-485 wiring
Connect the devices on the RS-485 bus in a point-to-point configuration, with the
(+) and (-) terminals from one device connected to the corresponding (+) and (-)
terminals on the next device.

- -
+ +
120 Ω
NOTE:
Straight-line topology only. Loop or ring topology is not supported.
Resistor is an optional accessory that you can order separately. To terminate a
series, it is recommended to use a 120 Ω / 0.5 W resistor.

NHA2768503-07 19
EasyLogic™EM6400NG+ Hardware references

RS-485 cable
Use a shielded 2 wires or 1 twisted pair RS-485 cable to wire the devices. Use the
twisted pair to connect the (+) and (-) terminals.

RS-485 terminals
C Common. This provides the voltage reference (zero volts) for the data plus and data minus
signals

Shield. Connect the bare wire to this terminal to help suppress signal noise that may be
present. Ground the shield wiring at one end only (either at the master or the last slave
device, but not both.

- Data minus. This transmits/receives the inverting data signals.

+ Data plus. This transmits/receives the non-inverting data signals.

NOTE: If some devices in your RS-485 network do not have the C terminal,
use the bare wire in the RS-485 cable to connect the C terminal from the
meter to the shield terminal on the devices that do not have the C terminal.

RS-485 maximum cable length

The total distance for devices connected on an RS-485 bus should not exceed
900 m (2953 ft).

RS-485 network configuration

After you have wired the RS-485 port and powered up the meter, you must
configure the serial communications port in order to communicate with the meter.
Each device on the same RS-485 communications bus must have a unique
address and all connected devices must be set to the same protocol, baud rate,
and parity (data format).
NOTE: To communicate with the meter using ION Setup, you must set the
serial site and all connected devices in the RS-485 network to the same parity
setting.

Pulse output
The meter is equipped with one pulse output port (D1+, D0-).
You can configure the pulse outputs for use in the following application:
• Energy pulsing applications, where a receiving device determines energy
usage by counting the k_h pulses coming from the meter’s pulse output port.
One pulse output can handle voltage less than or equal to 40 V DC (20 mA
maximum). For higher voltage applications, use an external relay in the switching
circuit.

Energy pulsing LED

The EM6400NG+ meter has an energy pulsing LED that can be configured for
energy pulsing.
This LED flashes at a rate proportional to the amount of energy consumed. This is
typically used to verify the meter’s accuracy.
NOTE: EM6400NG+ meter does not support alarm function.

Heartbeat / serial communications LED

The heartbeat / serial communications LED blinks to indicate the meter’s
operation and serial Modbus communications status.
The LED blinks at a slow, steady rate to indicate the meter is operational. The LED
flashes at a variable, faster rate when the meter is communicating over a Modbus
serial communications port.
You cannot configure this LED for other purposes.
NOTE: A heartbeat LED that remains lit and does not blink (or flash) can
indicate a problem. In this case, power down the meter and reapply power. If
the LED still does not blink or flash, contact Technical Support.

Button functions
The meter supports single press and combination press functions of the buttons.

Measurements and calculations

Meter initialization
Meter Initialization is a special command that clears the meter’s energy, power,
demand values, and meter operation timer.
It is common practice to initialize the meter after its configuration is completed,
before adding it to an energy management system.
After configuring all the meter setup parameters, navigate through the different
meter display screens and make sure the displayed data is valid then perform
meter initialization.
NOTE: You can perform meter initialization using ION setup and secured
command interface.

Real-time readings
The meter measures currents and voltages, and reports in real time the RMS
(Root Mean Squared) values for all three phases and neutral.
The voltage and current inputs are continuously monitored at a sampling rate of
64 samples per cycle. This amount of resolution helps enable the meter to provide
reliable measurements and calculated electrical values for various commercial,
buildings and industrial applications.

Energy measurements
The meter provides fully bi-directional, 4-quadrant energy metering.
The meter stores all accumulated active, reactive and apparent energy
measurements in nonvolatile memory:
• kWh, kVARh, kVAh (delivered)
• kWh, kVARh, kVAh (received)
• kWh, kVARh, kVAh net (delivered - received)
• kWh, kVARh, kVAh absolute (delivered + received)
All energy parameters represent the total for all three phases.
NOTE: Based on the energy scale selection, when kWh, kVARh, kVAh (delivered)
or kWh, kVARh, kVAh (received) of the energy parameters overflow at
999999999.999 all energy parameters value resets.

Quadrant based VARh

NOTE: Applicable only in EM6400NG+ RS-485 meter model.
Quadrant based reactive energy values are available only on communication.
These reactive energies are for Q1 , Q2, Q3 and Q4 quadrants.
On communication quadrant based reactive energies will be recorded as follows:
• Q1 (00 to 90 Degree) = Q1 VARh , Del
• Q2 (90 to 180 Degree) = Q2 VARh , Del
• Q3 (180 to 270 degree) = Q3 VARh, Rec
• Q4 (270 to 360 degree) = Q4 VARh , Rec

44 NHA2768503-07
Measurements and calculations EasyLogic™EM6400NG+

If energy is cleared, all quadrant based VARhs will be cleared.

Min/max values
When the readings reach their lowest or highest value, the meter updates and
saves these min/max (minimum and maximum) quantities in non-volatile memory.
The meter’s real-time readings are updated once every 50 cycles for 50 Hz
systems, or once every 60 cycles for 60 Hz systems.

Power demand
Power demand is a measure of average power consumption over a fixed time
interval.
NOTE: If not specified, references to demand are assumed to mean power
demand.
The meter measures instantaneous consumption and can calculate demand using
various methods.

Power demand calculation methods

Power demand is calculated by dividing the energy accumulated during a
specified period by the length of that period.
How the meter performs this calculation depends on the method and time
parameters you select (for example, timed rolling block demand with a 15-minute
interval and 5-minute subinterval).
To be compatible with electric utility billing practices, the meter provides the
following types of power demand calculations:
• Block interval demand
• Synchronized demand
• Thermal demand
You can configure the power demand calculation method from the display or
software.

Block interval demand

For block interval demand method types, you specify a period of time interval (or
block) that the meter uses for the demand calculation.
Select/configure how the meter handles that interval from one of these different
methods:

NHA2768503-07 45
EasyLogic™EM6400NG+ Measurements and calculations

Type Description

Timed Sliding Block Select an interval from 1 to 60 minutes (in 1-minute increments). If
the interval is between 1 and 15 minutes, the demand calculation
updates every 15 seconds. If the interval is between 16 and 60
minutes, the demand calculation updates every 60 seconds. The
meter displays the demand value for the last completed interval.

Timed Block Select an interval from 1 to 60 minutes (in 1-minute increments). The
meter calculates and updates the demand at the end of each
interval.
Timed Rolling Block Select an interval and a subinterval. The subinterval must divide
evenly into the interval (for example, three 5-minute subintervals for
a 15-minute interval). Demand is updated at the end of each
subinterval. The meter displays the demand value for the last
completed interval.

time clock.

46 NHA2768503-07
Measurements and calculations EasyLogic™EM6400NG+

Type Description

Command This method allows you to synchronize the demand intervals of multiple
synchronized demand meters on a communications network. For example, if a programmable
logic controller (PLC) input is monitoring a pulse at the end of a demand
interval on a utility revenue meter, you can program the PLC to issue a
command to multiple meters whenever the utility meter starts a new
demand interval. Each time the command is issued, the demand readings
of each meter are calculated for the same interval.
Clock synchronized This method allows you to synchronize the demand interval to the meter’s
demand internal real-time clock. This helps you synchronize the demand to a
particular time, typically on the hour (for example, at 12:00 am). If you
select another time of day when the demand intervals are to be
synchronized, the time must be specified in minutes from midnight. For
example, to synchronize at 8:00 am, select 480 minutes.

NOTE: For these demand types, you can choose block or rolling block
options. If you select a rolling block demand option, you need to specify a
subinterval.

Thermal demand
Thermal demand calculates the demand based on a thermal response, which
imitates the function of thermal demand meters.
The demand calculation updates at the end of each interval. You can set the
demand interval from 1 to 60 minutes (in 1-minute increments).

Thermal demand example

The following illustration shows the thermal demand calculation. In this example,
the interval is set to 15 minutes. The interval is a window of time that moves
across the timeline. The calculation updates at the end of each interval.

Current demand
The meter calculates current demand using the block interval, synchronized or
thermal demand methods.
You can set the demand interval from 1 to 60 minutes in 1 minute increments (for
example, 15 minutes).

Predicted demand
The meter calculates predicted demand for the end of the present interval for kW,
kVAR, and kVA demand, taking into account the energy consumption so far within
the present (partial) interval and the present rate of consumption.
Predicated demand is updated according to the update rate of your meter.

Peak demand
The meter records the peak (or maximum) values for kWD, kVARD, and kVAD
power (or peak demand).
The peak for each value is the highest average reading since the meter was last
reset. These values are maintained in the meter’s non-volatile memory.
The meter also stores the date and time when the peak demand occurred.

Timer
The meter supports an active load timer, meter operation timer, and load run hours

Active load timer

Active load timer shows how much time a load has been running, based on the
specified minimum current for the load timer setpoint setting.
The active load timer data can be read through communication only.

Power quality EasyLogic™EM6400NG+

Power quality
Harmonics overview
This section describes the meter’s power quality features and how to access
power quality data. The meter measures voltage and current harmonics up to the
15th harmonic, and calculates Total Harmonic Distortion (THD%).
Harmonics are integer multiples of the fundamental frequency of the power
system. Harmonics information is required for compliance to system power quality
standards such as EN50160 and meter power quality standards such as IEC
61000-4-30.
The meter measures fundamental and higher harmonics relative to the
fundamental frequency. The meter’s power system setting defines which phases
are present and determines how line-to-line or line-to-neutral voltage harmonics
and current harmonics are calculated.
Harmonics are used to identify whether the supplied system power meets required
power quality standards, or if non-linear loads are affecting your power system.
Power system harmonics can cause current flow on the neutral conductor, and
damage to equipment such as increased heating in electric motors. Power
conditioners or harmonic filters can be used to minimize unwanted harmonics.

Total harmonic distortion %

Total harmonic distortion (THD%) is a measure of the total per-phase voltage or
current harmonic distortion present in the power system.
THD% provides a general indication of the quality of a waveform. THD% is
calculated for each phase of both voltage and current.

Harmonic content calculations

Harmonic content (HC) is equal to the RMS value of all the non-fundamental
harmonic components in one phase of the power system.
The meter uses the following equation to calculate HC:

HC = (H2)2 + (H3)2 + (H4)2 ...

THD% calculations
THD% is a quick measure of the total distortion present in a waveform and is the
ratio of harmonic content (HC) to the fundamental harmonic (H1).
By default, the meter uses the following equation to calculate THD%:
HC
THD = -------
- x 100%
H1

Displaying harmonics data

The meter displays voltage and current THD% data on the front panel, while the
phase wise THD% data can be read through communication.

NHA2768503-07 53
EasyLogic™EM6400NG+ Verifying accuracy

Verifying accuracy
Overview of meter accuracy
All meters are tested and verified at the factory in accordance with International
Electrotechnical Commission (IEC) and Institute of Electrical and Electronics
Engineers (IEEE) standards.
Your meter typically does not require re-calibration. However, in some installations
a final accuracy verification of the meters is required, especially if the meters will
be used for revenue or billing applications.

Accuracy test requirements

The most common method for testing meter accuracy is to apply test voltages and
currents from a stable power source and compare the meter’s readings with
readings from a reference device or energy standard.

Signal and power source

The meter maintains its accuracy during voltage and current signal source
variations but its energy pulsing output needs a stable test signal to help produce
accurate test pulses. The meter’s energy pulsing mechanism needs
approximately 10 seconds to stabilize after every source adjustment.
The meter must be connected to control power in order to conduct accuracy
verification testing. Refer to your meter’s installation documentation for power
supply specifications.

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
Verify the device’s power source meets the specifications for your device’s
power supply.
Failure to follow these instructions will result in death or serious injury.

Control equipment
Control equipment is required for counting and timing the pulse outputs from an
energy pulsing LED.
• Most standard test benches have an arm equipped with optical sensors to
detect LED pulses (the photodiode circuitry converts detected light into a
voltage signal).
• The reference device or energy standard typically has digital inputs that can
detect and count pulses coming from an external source (i.e., the meter’s
pulse output).
NOTE: The optical sensors on the test bench can be disrupted by strong
sources of ambient light (such as camera flashes, florescent tubes, sunlight
reflections, floodlights, etc.). This can cause test errors. Use a hood, if
necessary, to block out ambient light.

54 NHA2768503-07
Verifying accuracy EasyLogic™EM6400NG+

Environment
The meter should be tested at the same temperature as the testing equipment.
The ideal temperature is about 23 ºC (73 ºF). Make sure the meter is warmed up
sufficiently before testing.
A warm-up time of 30 minutes is recommended before beginning energy accuracy
verification testing. At the factory, the meters are warmed up to their typical
operating temperature before calibration to help ensure that the meters will reach
their optimal accuracy at operating temperature.
Most high precision electronic equipment requires a warm up time before it
reaches its specified performance levels. Energy meter standards allow the
manufacturers to specify meter accuracy derating due to ambient temperature
changes and self-heating.
Your meter complies with and meets the requirements of these energy metering
standards.
For a list of accuracy standards that your meter complies to, contact your local
Schneider Electric representative or download the meter brochure from
www.se.com.

Reference device or energy standard

To help ensure the accuracy of the test, it is recommended that you use a
reference device or reference energy standard with a specified accuracy that is 6
to 10 times more accurate than the meter under test. Before you start testing, the
reference device or energy standard should be warmed up as recommended by
its manufacturer.
NOTE: Verify the accuracy and precision of all measurement equipment used
in accuracy testing (for example, voltmeters, ammeters, power factor meters).

Verifying accuracy test

The following tests are guidelines for accuracy testing your meter; your meter
shop may have specific testing methods.

4. Connect the control equipment used for counting the standard output pulses
using one of these methods:

Option Description

Energy pulsing LED Align the red light sensor on the standard test bench armature over
the energy pulsing LED.

Pulse output Connect the meter’s pulse output to the standard test bench pulse
counting connections.

NOTE: When selecting which method to use, be aware that energy

pulsing LEDs and pulse outputs have different pulse rate limits.
5. Before performing the verification test, let the test equipment power up the
meter and apply voltage for at least 30 seconds. This helps stabilize the
internal circuitry of the meter.
6. Configure the meter’s parameters for verifying accuracy testing.
7. Depending on the method selected for counting the energy pulses, configure
the meter’s energy pulsing LED or one of the pulse outputs to perform energy
pulsing. Set the meter’s energy pulse constant so it is in sync with the
reference test equipment.
8. Perform accuracy verification on the test points. Run each test point for at
least 30 seconds to allow the test bench equipment to read an adequate
number of pulses. Allow 10 seconds of dwell time between test points.

Required pulses calculation for accuracy verification

testing
Accuracy verification test equipment typically requires you to specify the number
of pulses for a specific test duration.
The reference test equipment typically requires you to specify the number of
pulses required for a test duration of “t” seconds. Normally, the number of pulses
required is at least 25 pulses, and the test duration is greater than 30 seconds.
Use the following formula to calculate the required number of pulses:

56 NHA2768503-07
Verifying accuracy EasyLogic™EM6400NG+

Number of pulses = Ptot x K x t/3600

Where:
• Ptot = total instantaneous power in kilowatts (kW)
• K = the meter’s pulse constant setting, in pulses per kWh
• t = test duration, in seconds (typically greater than 30 seconds)

Total power calculation for accuracy verification testing

Accuracy verification testing supplies the same test signal (total power) to both the
energy reference/standard and the meter under test.
Total power is calculated as follows, where:
• Ptot = total instantaneous power in kilowatts (kW)
• VLN = test point line-to-neutral voltage in volts (V)
• I = test point current in amps (A)
• PF = power factor
The result of the calculation is rounded up to the nearest integer.
For a balanced 3–phase Wye system:
Ptot = 3 x VLN x I x PF x 1 kW/1000 W
NOTE: A balanced 3–phase system assumes that the voltage, current and
power factor values are the same for all phases.
For a single-phase system:
Ptot = VLN x I x PF x 1 kW/1000W

Percentage error calculation for accuracy verification

testing
Accuracy verification testing requires you to calculate the percentage error
between the meter being tested and the reference/standard.
Calculate the percentage error for every test point using the following formula:
Energy error = (EM - ES) / ES x 100%
Where:
• EM = energy measured by the meter under test
• ES = energy measured by the reference device or energy standard.
NOTE: If accuracy verification reveals inaccuracies in your meter, they may be
caused by typical sources of test errors. If there are no sources of test errors
present, please contact your local Schneider Electric representative.

Accuracy verification test points

The meter should be tested at full and light loads and at lagging (inductive) power
factors to help ensure testing over the entire range of the meter.
The test amperage and voltage input rating are labeled on the meter. Refer to the
installation sheet or data sheet for your meter’s nominal current, voltage and
frequency specifications.

frequency at unity power factor or one (1).

power factor) frequency at 0.50 lagging power factor (current lagging voltage by 60°

Full load 100% to 200% of the nominal current, 100% of the nominal voltage and
nominal frequency at zero power factor (current lagging voltage by 90°

Light load 10% of the nominal current, 100% of the nominal voltage and nominal
frequency at zero power factor (current lagging voltage by 90° phase
angle).

Inductive load (lagging 100% of the nominal current, 100% of the nominal voltage and nominal
power factor) frequency at 0.87 lagging power factor (current lagging voltage by 30°
phase angle).

Energy pulsing considerations

The meter’s energy pulsing LED and pulse outputs are capable of energy pulsing
within specific limits.

Description Energy pulsing LED Pulse output

Maximum pulse frequency 35 Hz 20 Hz

Minimum pulse constant 1 pulse per k_h

Maximum pulse constant 9,999,000 pulses per k_h

The pulse rate depends on the voltage, current and PF of the input signal source,
the number of phases, and the VT and CT ratios.
If Ptot is the instantaneous power (in kW) and K is the pulse constant (in pulses
per kWh), then the pulse period is:
3600 1
Pulse period (in seconds) = =
K x Ptot Pulse frequency (Hz)

VT and CT considerations
Total power (Ptot) is derived from the values of the voltage and current inputs at
the secondary side, and takes into account the VT and CT ratios.
The test points are always taken at the secondary side, regardless of whether VTs
or CTs are used.
If VTs and CTs are used, you must include their primary and secondary ratings in
the equation. For example, in a balanced 3-phase Wye system with VTs and CTs:
VTp CTp 1 kW
Ptot = 3 x VLN x xIx x PF x
VTs CTs 1000 W
where Ptot = total power, VTp = VT primary, VTs = VT secondary, CTp = CT
primary, CTs = CT secondary and PF = power factor.

Verifying accuracy EasyLogic™EM6400NG+

Example calculations
This example calculation shows how to calculate power, pulse constants and
maximum pulse frequency, and how to determine a pulse constant that reduces
the maximum pulse frequency.
A balanced 3-phase Wye system uses 480:120 volt VTs and 120:5 amp CTs. The
signals at the secondary side are 119 volts line-to-neutral and 5.31 amps, with a
power factor of 0.85. The desired pulse output frequency is 20 Hz (20 pulses per
second).
1. Calculate the typical total output power (Ptot):

Ptot = 3 x 119 x 480 x 5.31 x 120 x 0.85 x 1 kW = 154.71 kW

120 5 1000 W

2. Calculate the pulse constant (K):

3600 x (pulse frequency) = 3600 seconds/hour x 20 pulses/second
K=
Ptot 154.71 kW

K = 465.5 pulses / kWh

3. At full load (120% of nominal current = 6 A) and power factor (PF = 1),
calculate the maximum total output power (Pmax):

Pmax = 3 x 119 x 480 x 6 x 100 x 1 x 1 kW = 205.6 kW

120 5 1000 W
4. Calculate the maximum output pulse frequency at Pmax:

Maximum pulse frequency = K x Pmax = 465.5 pulses / kWh x 205.6 kW

3600 3600 seconds/hour
Maximum pulse frequency = 26.6 pulses/second = 26.6 Hz
5. Check the maximum pulse frequency against the limits for the LED and pulse
outputs:
• 26.6 Hz ≤ LED maximum pulse frequency (35 Hz)
• 26.6 Hz > pulse output maximum pulse frequency (20 Hz)
NOTE: The maximum pulse frequency is within the limits for LED energy
pulsing. However, the maximum pulse frequency is greater than the limits
for pulse output energy pulsing. Pulse output frequencies greater than 20
Hz will saturate the pulse output and cause it to stop pulsing. Therefore in
this example, you can only use the LED for energy pulsing.

Adjustments to allow energy pulsing at the pulse outputs

If you want to use the pulse output, you must reduce the output pulse frequency
so it is within the limits.
Using the values from the above example, the maximum pulse constant for the
pulse output is:

3600 x (pulse output maximum pulse frequency)

Kmax = = 3600 x 20
Pmax 205.6
Kmax = 350.14 pulses per kWh

NHA2768503-07 59
EasyLogic™EM6400NG+ Verifying accuracy

1. Set the pulse constant (K) to a value below Kmax, for example, 300 pulses/
kWh. Calculate the new maximum output pulse frequency at Pmax:

New maximum pulse frequency = K x Pmax = 300 pulses/kWh x 205.6 kW

3600 3600 seconds/hour
New maximum pulse frequency = 17.1 pulses/second = 17.1 Hz
2. Check the new maximum pulse frequency against the limits for the LED and
pulse outputs:
• 17.1 Hz ≤ LED maximum pulse frequency (35 Hz)
• 17.1 Hz ≤ pulse output maximum frequency (20 Hz)
As expected, changing K to a value below Kmax allows you to use the pulse
output for energy pulsing.
3. Set the new pulse constant (K) on your meter.

Typical sources of test errors

If you see excessive errors during accuracy testing, examine your test setup and
test procedures to eliminate typical sources of measurement errors.
Typical sources of accuracy verification testing errors include:
• Loose connections of voltage or current circuits, often caused by worn-out
contacts or terminals. Inspect terminals of test equipment, cables, test
harness and the meter under test.
• Meter ambient temperature is significantly different than 23 °C (73 °F).
• Floating (ungrounded) neutral voltage terminal in any configuration with
unbalanced phase voltages.
• Inadequate meter control power, resulting in the meter resetting during the
test procedure.
• Ambient light interference or sensitivity issues with the optical sensor.
• Unstable power source causing energy pulsing fluctuations.
• Incorrect test setup: not all phases connected to the reference device or the
energy standard. All phases connected to the meter under test should also be
connected to the reference meter/standard.
• Moisture (condensing humidity), debris or pollution present in the meter under
test.

Power and power factor

Power and power factor
The sampled measurements taken at the meter’s voltage and current inputs
provide data for calculating power and power factor.
In a balanced 3-phase alternating current (AC) power system source, the AC
voltage waveforms on the current-carrying conductors are equal but offset by one-
third of a period (a phase angle shift of 120 degrees between the three voltage
waveforms).

Current phase shift from voltage

Electrical current can lag, lead, or be in phase with the AC voltage waveform, and
is typically associated with the type of load — inductive, capacitive or resistive.
For purely resistive loads, the current waveform is in phase with the voltage
waveform. For capacitive loads, current leads voltage. For inductive loads, current
lags voltage.
The following diagrams show how voltage and current waveforms shift based on
load type under ideal (laboratory) conditions.

Current and voltage in phase (resistive) Current leads voltage (capacitive) Current lags voltage (inductive)

Real, reactive and apparent power (PQS)

A typical AC electrical system load has both resistive and reactive (inductive or
capacitive) components.
Real power, also known as active power (P) is consumed by resistive loads.
Reactive power (Q) is either consumed by inductive loads or generated by
capacitive loads.
Apparent power (S) is the capacity of your measured power system to provide real
and reactive power.
The units for power are watts (W or kW) for real power P, vars (VAR or kVAR) for
reactive power Q, and volt-amps (VA or kVA) for apparent power S.

Power flow
Positive real power P(+) flows from the power source to the load. Negative real
power P(-) flows from the load to the power source.

Power factor (PF)

Power factor (PF) is the ratio of real power (P) to apparent power (S).
PF is provided as a number between -1 and 1 or as a percentage from -100% to
100%, where the sign is determined by the convention.
P
PF = —
S

A purely resistive load has no reactive components, so its power factor is 1 (PF =
1, or unity power factor). Inductive or capacitive loads introduce a reactive power
(Q) component to the circuit which causes the PF to become closer to zero.

True PF and displacement PF

The meter supports true power factor and displacement power factor values:
• True power factor includes harmonic content.
• Displacement power factor only considers the fundamental frequency.
NOTE: Unless specified, the power factor displayed by the meter is true power
factor.

Power and power factor EasyLogic™EM6400NG+

Power factor sign convention

Power factor sign (PF sign) can be positive or negative, and is defined by the
conventions used by the IEEE or IEC standards.
You can set the power factor sign (PF sign) convention that is used on the display
to either IEC or IEEE.

PF sign convention: IEC

PF sign correlates with the direction of real power (kW) flow.
• Quadrant 1 and 4: Positive real power (+kW), the PF sign is positive (+).
• Quadrant 2 and 3: Negative real power (-kW), the PF sign is negative (-).

PF sign convention: IEEE

PF sign is correlates with the PF lead/lag convention, in other words, the effective
load type (inductive or capacitive):
• For a capacitive load (PF leading, quadrant 2 and 4), the PF sign is positive
(+).
• For an inductive load (PF lagging, quadrant 1 and 3), the PF sign is negative
(-).

PF value display
First digit of PF value indicates the Lag and Lead.
Lag is indicated by “i” and Lead is indicated by “c” for first digit of PF value.
NOTE: “i” = Inductive load/Lag PF and “c” = capacitive load/Lead PF.
NOTE: Without the load, the PF value is displayed as “- - - -”

Power factor min/max convention

The meter uses a specific convention for determining the power factor minimum
and maximum values.
• For negative PF readings, the minimum PF value is the measurement closest
to -0 for PF readings between -0 to -1. For positive PF readings, the minimum
PF value is the measurement closest to +1 for PF readings between +1 to +0.
• For negative PF readings, the maximum PF value is the measurement
closest to -1 for PF readings between -0 to -1. For positive PF readings, the
maximum PF value is the measurement closest to +0 for PF readings
between +1 to +0.
