Earth Leakage Relays Earth leakage relays play two very important roles in electrical systems ‒ protection of human beings from electrocution and safety from fire. Leakage current through very small in magnitude can wreak havoc in the installations. ...
Only the leakage current will be shown in register address 151. Another address 149 is a dummy. 1. Current R Phase 40151 = Leakage current of iELR 2.Current Average 40149 = Dummy
