A selective single-phase-to-ground fault protection for neutral un-effectively grounded systems
International Journal of Electrical Power & Energy Systems, 2011 Single-phase-to-ground faults are the most frequent faults likely to occur in power distribution networks. As for a neutral un-effectively grounded system (NUGS), the low fault current is very common in the case of occurrence of a single-phase earth fault, leading to hard identification of the faulty feeder.

Fault Path Direct-Current Resistance Based Off-Line Single-Phase-To-Ground Fault Location
Zhongguo dianli, 2021 In order to figure out the off-line transmission line fault location, a new fault location method based on fault path direct current resistance measurement is proposed. Firstly, an off-line fault detection and diagnosis method based on three-phase insulation resistance measurement is proposed, including fault type and fault phase diagnosis.
