Abstract

Partial-discharge (PD) characteristics in three gases (air, argon and helium) at pressures between 101 kPa (760 Torr) and about 0.27 kPa (2 Torr) under 60-Hz ac energization were studied. Measurements for two representative electrode configurations showed that the electrical characteristics of PD (specifically, electric pulse waveforms) at low pressures differ significantly from those at sea-level pressures. Difficulties in obtaining accurate measurements when adhering to guidelines defined by the IEC 60270 standard are described. Suggested modifications of the standard procedures are presented for measurement and calibration for low-pressure PD.
