| Working | 1] If the Input supply is within the range of the fault limits then On Timer starts decrementing on display & after Set On Time over Relay will be ON with RLY indication glowing.; 2] If OV, UV, Spp, Unbalance occurs in the supply then Relay will be OFF after the trip delay of that particular fault.; 3] If any Phase to Phase Voltage increases above OV set point, Relay will trip after trip delay (<100 ms) over. If that particular phase to phase voltage reduces below (OV set point - 10 V), Relay wi |
