Abstract:When the single-phase ground fault appears in the non-neutral point earthing system, the circuit breaker does not trip automatically because the rules allow the system to go on working for a period of time. DML finder may help the operators detect with electrici-ty the troubled outlet line quickly, determine troubled branch line and locate the position of fault accurately. DML finder may be used as the electroscope, too.This paper describes the ground fault-detecting principles, structural components, con-trollers, indicators and so on.
Keywords:harmanic wave  detection  wave trap  amplifier  buffer  driver
