High earth leakage
Webtransformer often leads to high earth leakage currents under normal operation. The effect becomes more pronounced as higher system voltages are introduced. This implies that the jump from low-to-medium voltage requires a rethinking regarding the design. Especially (but not exclusively) for underground mining, high earth leakage currents are not Web15 de ago. de 2016 · Vinay5794. Aug 5, 2016. #1. Hi everyone!! Here in a process plant we have been dealing with a severe problem. A 315kW, 6.6kV fed compressor motor is very frequently Tripping on Earth Fault while starting by 7SJ600 O/C relay. We have checked everything we could do. We have changed CT's, relay everything. The settings are same …
