Influence of indirect frequency converters on operation of central leakage protection in underground coalmine networks This paper presents considerations for leakage protections operating in underground coalmine networks containing loads that include frequency converters. The possibility of malfunctions in leakage protections has been proven in the case of a reduction of leakage resistance in a DC circuit.
