3.7 Device description
The device is suitable for
·Measurements and calculations of electric
values such as voltage, current, power,
energy, harmonics in the building installation,
at distributors, circuit breakers and busbar
trunking systems.
·Measuring voltages and currents originating
from the same network.
·Measurements in low-voltage networks in
which rated voltages of up to 417 V conductor
to ground and surge voltages of overvoltage
category III occur.
·Measurements in medium and high-voltage
networks with current and voltage transformers.
Generally, current and voltage transformers
perform measurements in medium and high
voltage networks!
·Current measurement via external ../1 A or
../5 A current transformer.
·Installation in permanently installed switch
cabinets or small installation distributors, in any
installation position.
·Use in residential and industrial sectors.
The measuring device shows the measurement
results, whereas the measurement results are
read and processed further via the interface.
3.8 Measurement method
The device measures
·seamlessly and calculates all effective values
within a 200 ms interval.
·the true effective value (TRMS) of the voltages
and currents generated at the measurement
inputs.
3.9 Operating concept
The measuring device’s operating concept
consists of the following methods:
·
6 function keys with display
to configure and
record data.
·The
network analysis and programming
software GridVis
®
for data programming and
analysis
.
·The
Modbus protocol and the Modbus
address list
for data configuration and export.
You can find the Modbus address list on
www.janitza.de.
This user manual only describes the operation of
the device via the 6 function keys. The GridVis
®
network analysis software has its own “Online
help” and e-learning modules.
3.10 GridVis
®
network analysis software
Use the GridVis
®
network analysis software
available on www.janitza.de to program your
measuring device and to export data for analysis.
To do so, connect a PC, for example via the
serial interface (RS485) or a gateway (such as
UMG 512-PRO) to your measuring device.
Use the GridVis
®
network analysis software to:
·Program your device.
·Configure and export recordings.
·Analyze the exported data.
·Save the data in databases.
·Graphically illustrate the measured values.
·Program custom applications.
ATTENTION
Malfunction or damage to the device due to
improper connection.
Improperly connected devices can deliver
incorrect measured values or damage the
device.
Please observe the following:
·
The measured voltages and measured
currents originate from the same network.
·
Do not use the device to measure DC
current!
·
Ground conductive switchboards!
