Novel protection scheme of stator single-phase-to-ground fault for powerformers
The stator single phase-to-ground fault protection for parallel powerformers. Protection scheme is based on fuzzy clustering algorithms. Space relative distance is calculated to discriminate faulted powerformer. Powerformers can be detected in 100% of the winding with resistance 5k?.
