Dependence of creeping partial discharge activity in a synthetic esters-paper insulating system on the temperature

The paper presents the results of partial discharges investigation in a synthetic ester-paper insulating system for three values of temperature (25°C, 30°C and 40°C). The article shows the measurement set-up, measuring procedure, data outcome and its analysis. It occurs, that there is a positive correlation between temperature and PD's activity in investigated set-up.
