In this paper, the current research status of partial discharge (PD) measurement using non-sinusoidal voltage waveforms at home and abroad were summarized, the PD characteristics under non-sinusoidal voltage waveforms such as continuous pulse square-wave voltage, triangular-wave voltage, and trapezoidal-wave voltage were reviewed, especially the effects of voltage rise time, frequency, and duty cycle of square-wave voltage on the PD activity were discussed deeply. Finally, the great significance and existing problems of PD measurements using non-sinusoidal voltage waveforms were discussed. Future development of PD measurements using non-sinusoidal voltage waveforms was proposed, and how to use the non-sinusoidal voltage waveforms to enhance the understanding of discharge physical process and insulation ageing mechanism were prospected.
