 Abstract

This paper presents a novel approach to diagnose interturn insulation faults in three-phase transformers that operate at differentloading conditions. This approach is based on the loci of instantaneous symmetrical components and requires the measurement ofthree input primary winding currents and voltages to diagnose faults in the transformer. The effect of unbalance supply conditions,load variations, constructional imbalance, and measurement errors when this methodology is used is also investigated. Wing size orlength determines the loading on the transformer. Wing travel and area determine the degree of severity of fault. Experimentalresults are presented for a 400/200 V, 7.5 kVA transformer to validate this method.
