Abstract :
There is a lack of knowledge on the role of the gas chemistry in the ageing of materials in air insulated electrical equipment. This paper aims to provide data on this subject through results obtained on one of the gaseous products (O3) generated by corona discharges, using a wire-to-plane geometry in ambient air, under continuous or alternating voltage. It is shown how its production depends both on the electrode material and on the gas humidity, and how results can be partly analysed in terms of plasma catalytic phenomena
