Frequency Response Testing of Zero-Sequence Current Transformers for Mining Ground Fault Protection Relays

In Polish coal mining, medium voltage power distribution networks operate with an insulated neutral point. Zero-sequence current transformers are the basic sensors that generate input signals for earth-fault protection relays. In the literature, the problem of frequency response analysis of various...
