FEATURES OF A FAULTY PHASE AT SINGLE PHASE-TO-GROUND FAULTS
Electrical and data processing facilities and systems, 2022 Relevance Devices for determining the location of fault on power lines assume a known type of short circuit and faulty phases. However, their algorithms, as a rule, can not distinguish the faulty phase. Therefore, the determination of faulty phases during short circuits on power lines is performed by separate devices – faulty phase selectors.

Energies, 2023 When the overhead line passes through the forest area, the conductor may contact the line to induce the tree-contact single-phase-to-ground fault (TSF), and the persistence of TSF may induce wildfires, bringing serious consequences.

Low-Resolution Fault Localization Using Phasor Measurement Units with Community Detection [PDF]
, 2018 A significant portion of the literature on fault localization assumes (more or less explicitly) that there are sufficient reliable measurements to guarantee that the system is observable. While several heuristics exist to break the observability barrier,

IET Generation, Transmission & Distribution, 2021 An improved natural frequency based method is proposed to accurately locate faults in transmission lines. The method only requires three phase instantaneous current measurements at the local terminal of the line and is compatible with protective relays ...
