Abstract :
This work reports the results of a basic research regarding the study of Partial Discharge (PD) behaviour in a flat cavity when the insulation is subjected to a square voltage waveform and to two different PWM-like voltage waveforms. Tests were performed on CIGRE II specimens realised using polyimide film samples.
