UMG 511
The UMG511 has 4 measurement channels for
current measurement (I1..I4) and 4 measurement
channels for voltage measurement (V1..V4 against
Vref).
Measurement voltages and measurement currents
for measurement channels 1-4 must come from
the same network.
Main measurement
Measurement channels 1-3 are part of the main
measurement. Use measurement channels 1-3 in
three-phase systems.
Auxiliary measurement
Measurement channel 4 only belongs to auxilia-
ry 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 set-
tings for the main measurement.
Measurement
Configure here:
• The measurement transformers for the
current and voltage measurement
• The record of transients
• The recording of events
• The voltage mode
• The rated frequency
• The flicker setting
