Voltage Phase Reversal
Description
The voltage phase reversal protection function helps to identify the wrong wiring of three-phase voltage.
The voltage phase reversal protection function generates the following signals:
-
Alarm: If the detected voltage phase sequence is not matching with the phase rotation setting .
-
Trip: If the detected voltage phase sequence is not matching with the phase rotation setting, for the specified time delay.
