Abstract

This paper describes in detail, field experiments performed on a single-phase, distribution transformer to study the behavior of transformer terminal parameters during internal winding faults. A custom-built transformer provided with external taps was used for these tests. The taps were used to stage various internal winding faults in the transformer. Terminal values of voltages and currents were monitored and the results presented. A comparison of these results with simulation results is also presented
