After a long in-service period, the electrical aging phenomenon of Nylon 6 may cause insulation degradation. Most of the researches focus on AC/DC or room temperature conditions. Less attention is paid to the nanosecond pulses conditions. In this paper, frequency effect on the electrical tree growth of nylon 6 was investigated. A solid-state pulse generator MPC50D was used to export nanosecond pulses...
Polytetrafluoroethylene (PTFE) has been widely used in insulation equipment and high voltage apparatus due to its excellent insulating property. However, electrical aging phenomenon of PTFE may cause insulation failure under nanosecond pulses. Temperature is an important parameter that influences the electrical aging process. This paper investigated the effect of temperature on the electrical aging...
