SICAM Q100 – Description

Description
The SICAM Q100 multifunctional measuring device is used for
acquisition, visualization, evaluation and transmission of elec-
trical measured variables such as alternating current, alternating
voltage, frequency, power, harmonics etc. The acquisition,
processing and accuracy of measured variables and events are
performed according to the IEC 61000-4-30 Class A power
quality measurement standard. The measured variables can be
output to a PC or system control via communication interfaces
or shown on a display. In addition to the monitoring function,
the SICAM Q100 all-in-one device provides a combined
2.3 recording and evaluating function: measured values can be
recorded in parameterizable time intervals with various
recorders such as power quality and fault recorders. Long-time
data and events are evaluated directly in the device and
displayed as a report according to the power quality standards
(e.g., EN 50160).
The Modbus Gateway function supports RS485 devices (e.g.,
PAC 3100, 3200, SICAM P50) to connect to your Modbus TCP
network, reducing cabling and converter costs, and more flex- [ph_SICAM_Q100_W3_1.0_ISO2, 1, --_--]

Communication
SICAM Q100 has an Ethernet interface and an electric RS485
interface.
Ethernet supports the device parameterization, transmission of
measured data, metered values, load profiles, and indications/
events and the time synchronization with NTP. The communica-
tion protocols used are HTTP, Modbus TCP, and IEC 61850
server.
The RS485 interface supports the transmission of measured
data, metered values, load profiles, and indications and the time
synchronization. The communication protocol is Modbus RTU.
The integrated Ethernet switch in the device allows cascading
further network components (SICAM subdevices) via a Y cable
and integrating them in an existing network with IEC 61850 or
another Ethernet protocol.

Time Synchronization
During operation SICAM Q100 needs the date and time for all
time-relevant processes. This ensures that a common time basis
exists when communicating with peripheral devices and enables
time stamping of the process data.

Trend Recorder
The trend recorder guarantees the continuous acquisition and
long-term monitoring of the voltage VRMS (1/2). This new RMS
value is recorded when, during the parameterized measuring
interval, the change of the measured quantity against the last
measured RMS value is outside the selected tolerance range.

Sine Recording
Sine recording records 2048 sampled values per 10/12 system
periods in selectable time units. The sine recording function can
be activated for the measurands voltage and current. For event
analysis, you can select a pre-trigger time (pre-trigger ratio in %)
so that the history of the measurement before the fault incep-
tion can be analyzed.

SICAM Q100 – Energy Management

Energy Management
As part of the energy management, SICAM Q100 records load
profiles according to the Fixed Block and Rolling Block method
for all power quantities. Additionally, it is possible to calculate
up to 4 tariffs (TOU = Time of Use). The synchronization is made
with external or internal triggers.

Storage of Load-Profile Data

The load-profile data are stored in a ring buffer with up to 4 000
datasets. Every new dataset overwrites the oldest dataset. Every
2.3 dataset contains the average power values, minimum/maximum
values, a time stamp, and status information for a completed
subperiod.
The traceability of the load profile depends on the length of the

The arithmetic average power values and the extreme values
per subperiod are stored in the ring buffer. The cumulated
power values can be retrieved via communication or displayed
in the user interface.

Rolling Block Method

A measuring period of the Rolling Block method consists of 2 to
5 subperiods depending on the parameterization.
The length of a measuring period is the product of the number
of subperiods and the parameterized length of the subperiod.

Tariffs
SICAM Q100 supports up to 4 tariffs for power meters for
supplied or consumed active energy, reactive energy, and appa-
rent energy. If the tariff change is controlled, up to 4 tariffs can
be set. If tariffs are changed via binary inputs, up to 2 tariffs can
be set. The value of the binary inputs which there is at the time
of the beginning of the subperiod at the binary input is decisive
for it.
The tariff is changed via the external interfaces. A time-related
tariff change is only possible by a superordinate system.

[sc_tariffs_ISO2, 1, en_US]

Figure 2.3/6 Evaluation Tariffs

Tariff Change on Load-Profile Synchronization

The recorded load profile is always assigned to the current tariff.
If, during a running measuring period, a tariff change is made,
for instance, from high to low tariff, this has initially no effect
on the load-profile recording.
The new tariff becomes effective in the load-profile recording
and in the power meters of SICAM Q100 only with the start of
the next measuring period.

Tariff Change without Load-Profile Synchronization

If no external and internal synchronization of the load profile is
performed, the tariff change becomes effective immediately. A
tariff change without synchronization exists if in the parameteri-
