The item "Thresholds Annex A70" allows you to read and configure positive sequence undervoltage,
negative sequence overvoltage and residual overvoltage thresholds. These thresholds can be
enabled independently.
It also possible to set the quiescent status of the various relay used as remote signals as normally de-
energized (selection "OFF"), or normally energized (selection "ON"), and also the trip matrix related to
relay TS51A and TS67AV for the voltage thresholds perviously indicated.
