DESIGN AND OPERATION
The relay measures the line current from each of the phases and if exceeds the set operating
current, then relay extends a trip signal after the operating time. The relays operating time is
determined by selecting one of the four inverse time current characteristics. The relay has facility
to active / inhibit the high set protection feature. The relay output contacts are self reset type.
Relay operation without any fault current is determinated by trip test facility
