Estimating transformer parameters for partial discharge location

Hettiwatte, S.N., Wang, Z.D. and Crossley, P.A. (2014) Estimating transformer parameters for partial discharge location. In: Australasian Universities Power Engineering Conference (AUPEC2014), 28 September - 1 October, Perth, Western Australia



Partial discharge (PD) location in power transformers using electrical methods require transformer parameters to estimate the PD location. Previous research using a lumped parameter model of a transformer consisting of inductance (L), series capacitance (K) and shunt capacitance (C) has shown an algorithm for PD location. This algorithm does not require L, K and C values for the transformer in their explicit form. Rather, the products LC and LK are required. This paper presents three methods of estimating LC and LK values for a power transformer, which could then be used for PD location. The paper shows that all three methods give identical results confirming that either of these methods could be used for estimating LC and LK values. Results based on impedance measurements from two transformer windings are also presented.
