The use of phase voltage modules to select the damaged phase in case of single-phase earth faults [PDF]
Омский научный вестник, 2023 In case of short circuits, the selection of damaged phases always precedes the determination of the damage location. To select the damaged phase, filter selector of the damaged phase are widely used, using symmetrical components of phase currents.
