Locating partial discharge (PD) using single-pulse analysis is considered in this research. The studied network is a generator connected to a transformer through the busbar. Since the stator winding of a generator consists of a finite number of wound coils and finite length busbar, an analysis based on a simple ladder transmission-line model with a finite number of sections has been carried out. A simulation study using the SIMULINK package on the model produces network frequency responses under varied line parameters, and a varied number of sections and termination conditions. The investigation shows that the results of simultaneous PD measurements at different locations can be reproduced satisfactorily using the network model in terms of predicting its resonant frequencies and the time-domain envelope profile of the PD. The proposed method enables one to discriminate PD pulses originating from different locations of the generator winding, as it is observed that the PD magnitude attenuates during propagation.
