FEATURES OF A FAULTY PHASE AT SINGLE PHASE-TO-GROUND FAULTS

open access: yesElectrical 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.
