High Vzps Alarm

The Directional Blocking facility includes a High ZPS Voltage alarm. This indication can be useful in unearthed neutral networks for earth fault detection.

The high Vzps alarm is asserted whenever the Alarm Set-point is exceeded for the Alarm Timeout period. Regardless of whether SEF protection is picked up or not. The alarm is cleared when Vzps falls below the Alarm Set-point again.

The High Vzps Alarm can be turned on and configured via WSOS on the Directional Blocking page.
