With the rapid development of the electric power industry, the parameters of the units and the voltage level of the system are gradually increasing. The insulation strength of the electrical equipment and the limit level of the system overvoltage have an increasingly prominent impact on the safe and economical operation of the system. According to statistics, various faults in the high-voltage power grid are mostly caused by the damage of the insulation of the high-voltage electrical equipment. Therefore, understanding the insulation characteristics of the equipment, mastering the insulation status, and continuously improving the insulation level of the electrical equipment are the fundamental guarantees for the safe and economical operation of the power system.
