Abstract

Abstract : This study presents the simulation experiment of the partial discharge (PD) signal transmitted by the generator in the excitation transformer. Firstly, voltage over the low‐voltage winding of the excitation transformer was displayed. The degradation process of the insulation and the PD online monitoring method were described. Electrical circuit was established by the electro‐magnetic transients program (EMTP) software, which was simulated PD signal from generator propagation in the excitation transformer. Results show that simulation model was right and benefited to fault diagnosis of PD signals in the excitation transformer.
