Abstract

Partial discharge in gas insulated switchgear is a well-known phenomenon that can be an indicator of insulation ageing and degradation. It is vital to analyse and post-process these signals under different humidity, pressure, dielectric gaseous media, contamination, pressure, temperature and voltage waveforms in order to understand the severity of the underlying defect in a practical system. In this paper, an initial prototype including coupling device and external measurement system with phase-resolved partial discharge data processing methods is introduced to study the effects of the aforementioned parameters, which may lead to greater insights into defect type and severity in eco-friendly alternative insulating gases.
