Influence of humidity on conduction processes in gas-insulated devices

Influence of humidity on conduction processes in gas-insulated devices

Humidity has been considered as one of the main influencing factors that determine the conduction processes and electric strength of gas-insulated systems. Whereas in the past, various studies focused on the change in the partial discharge inception voltages, breakdown strength of homogeneous and in...
