Abstract	In order to study the partial discharge (PD) pulses under oscillatory impulse voltage (OIV), an oscillation waveform generator is designed and the waveform parameters expressions are presented based on the equivalent circuit model; A high-frequency current transducer is developed for measurement of PD. Then the effects of coil turns and integral resistance on frequency properties are studied. Moreover, calibration and analysis of the actual dynamic response are performed by adopting function generator and square-wave source; The PD measurement system to detect the PD signals of needle-plate model under OIV is provided finally. Experiment shows that by adopting this PD measurement system, the source interferences are restrained and PD signals are effectively extracted, therefore it could be a worthy approach not only for further study on PD character under OIV, but also to explore the mechanism behind it.
