The device is intended for:
• measuring power quality according
to EN61000-4-30 in building installations,
on distribution units, circuit breakers
and busbar trunking systems.
• measuring measured voltages and currents
that derive from the same network.
• measurements in low voltage networks
where rated voltages of up to 300 V and
surge voltages of overvoltage category III
can occur.
• installation in fixed switching cabinets
or small installation distributors. It can
be installed in any position.
• current measurement, for which it is
provided with external ../1 A or ../5 A
current transformers.
• use in 2, 3 and 4-conductor networks
and in TN and TT networks.
• measurements in medium and high-
voltage networks via current and voltage
transformers only.
The measurement results can be displayed,
read out and further processed via
the device's interfaces.
4. 1 Measuring process
The device measures continuously
and calculates all effective values over
a 200 ms interval.
The device measures the real effective
value (TRMS) of the voltages and currents
connected to the measurement inputs.
4. 2 Network failure detection
Network failure detection is carried
out via the voltage measurement inputs.
The selection of
voltage measurement inputs can be
configured using the GridVis® software.
The device bridges the following network
failures on the auxiliary voltage input:
• Supply voltage: 230 V AC
• Bridging time: max. 80 ms

NOTE!
Use the parameter list from “17.
Parameter list” for configuration
on the device and use the Modbus
address list on
www.janitza.de
for
configuration via a serial interface
4. 3 Usage concept
You can program and call up the measured
values via many routes using the device:
• Directly on the device via 2 buttons and
the display
• Using the GridVis® programming software
• Using the device homepage
• Using the Modbus protocol . You
can modify and call up the data using
the Modbus address list. The list can
be called up from www.janitza.de.
This user manual only describes how
to operate the device using the 2 buttons.
The GridVis® programming software has
its own "online help" system.
4. 4 GridVis® network analysis
software
You can use the GridVis® network analysis
software that is available at www.janitza.
de to program the device and read out
data. To do this, a PC must be connected
to the device via a serial interface (RS485/
Ethernet).
You can use the GridVis® network analysis
software to:
• program the device.
• configure and read out recordings.
• save the data to a database.
• display measured values graphically.
• program customer-specific applications.
