Abstract

Distribution transformers are subjected to impulse test prior to their installation in the field. The purpose of testing is to check internal insulation strength of transformer. In this research proposal a technique of impulse test of distribution transformer is presented in order to recognize type and approximate location of internal insulation faults. This paper will help the transformer manufacturer to become familiar with the type of fault and its location instantly by making comparison of faulty transformer waveform with the standard transformer test result. Moreover, rectification of fault can be made in more effective way with minimum time duration to improve the performance of manufacturing.
