The field tests to overvoltage level during the process of cutting on/off reactive power and the V-A characteristic of varistor used in the 220 V DC power supply system are carried out in the 220 kV Furong substation.The EMC and high temperature tests are developed to the model D25 multifunctional intelligence electronic equipment.The results indicate that the switch accident has nothing to do with the system switch and the overvoltage.
