Parameter New search after
If the zero sequence voltage Une stays smaller than the threshold value Umin during the
whole time, new search for the resonance point will start automatically when this time
has lapsed.
On symmetrical cable networks with big detuning, switching operation may only achieve
a small voltage change. The regulator must switched back AUTO mode either manually or
through the SCADA system.
Default setting: OFF:
