Faulty feeder detection based on transient attenuation and waveform similarity for low-resistance grounded system

In the case of a single-phase high-impedance fault (SPHIF) in a low-resistance grounded system (LRGS), the weak fault current makes it difficult to accurately detect the faulty feeder. To highlight the fault features, this paper first defines the concept of transient attenuation energy ratio and ana...
