Abstract

Power transformer is the most expensive single element of HV transmission system. Partial Discharge, mechanical displacement of the winding and inter-turn fault is commonly encountered problem in power transformer. This minor fault may lead to irretrievable damage. Transfer Function Method and Frequency Response Analysis Method are used in this paper, in order to locate the winding fault. The end result obtained for the different fault condition is compared with the reference set and the conclusions are drawn. Simulation is done with Orcad-Pspice and its results are verified with experimental setup.
