Voltage Connection Phase-to-Phase Voltage, Example
Voltage Difference
The parameters 6150 dV SYNCHK V2>V1 and 6151 dV SYNCHK V2<V1 can be set to adjust the permissible
voltage differences asymmetrically. The availability of two parameters enables an asymmetrical release to be
set.
Frequency Difference
The parameters 6152 df SYNCHK f2>f1 and 6153 df SYNCHK f2<f1 determine the permissible
frequency differences. The availability of two parameters enables an asymmetrical release to be set.
Operating Range
The parameters 6154 dα SYNCHK α2>α1 and 6155 dα SYNCHK α2<α1 delimit the operating range for
switching under synchronous system conditions. The availability of two parameters enables an asymmetrical
release range to be set.
Settings
Addresses which have an appended “A” can only be changed with DIGSI, under “Additional Settings”.
