Epoxy resin has been widely used as the dry-type insulation in high voltage direct current bushing. The temperature of the central conductor can go up to 90-105°C when working at the rated power flow. Thus, the inner insulation made of epoxy resin sustains these high temperatures. In order to study the effect of temperature on the dielectric performance, the space charge characteristics of epoxy resin at different temperatures (21, 40, 60, 80 and 100°C) have been studied with an improved pulsed… CONTINUE READING
