Measurement - janitza UMG511 Installation And Commissioning Manual

Measurement

The UMG511 has 4 measurement channels for
current measurement (I1..I4) and 4 measure-
ment channels for voltage measurement (V1..
V4 against Vref)
Measurement voltages and measurement
currents for measurement channels 1-4 must
come from the same network.

Parameterisation
Main measurement
Measurement channels 1-3 are part of the
main measurement. Use measurement chan-
nels 1-3 in three-phase systems.
Auxiliary measurement
Measurement channel 4 only belongs to auxil-
iary measurement. Use measurement channel
4 for measurements in single-phase systems
or in three-phase systems with symmetric
load.
The settings for the frequency and the relevant
voltage are automatically taken over from the
settings for the main measurement.
