5.8.6 Operation principle
Automatic switch onto fault logic, voltage and current based function (ZCVPSOF) can be activated
externally by Breaker Closed Input or internally (automatically) by using VI Level Based Logic see
figure 83.
The activation from the Dead line detection function is released if the internal signal deadLine
from the VILevel function is activated at the same time as the input ZACC is not activated during
at least for a duration
When the setting
get a trip one of the following operation modes must also be selected by the parameter
Mode = Impedance ; trip is released if the input ZACC is activated (normal connected to non
directional distance protection zone).
Mode = VILevel ; trip is released if VILevel detector is activated.
Mode = VILvl&Imp ; trip is initiated based on impedance measured criteria or VILevel detection.
The internal signal deadLine from the VILevel detector is activated if all three phase currents and
voltages are below the setting
Line distance protection REL650
