Abstract :
Partial discharges (PDs) are major sources of insulation failures in power transformers. A correlation method is proposed for the location of partial discharges within a transformer winding. Simulations are performed on lumped parameter models of layer, continuous disc and interleaved winding to prove the feasibility of the method.
