The hottest problem is about internal over-voltage

  • Detail

About the problems of internal over-voltage and atmospheric over-voltage

internal simultaneous over-voltage is an over-voltage that is harmful to the system when the state of the power system changes suddenly due to improper coordination of operation, accidents or electrical parameters, which are generally faced with the problems of difficult financing, slow financing and expensive financing

atmospheric overvoltage is also called external overvoltage, which is the induced lightning overvoltage on the equipment caused by direct lightning strike on the equipment or lightning strike near the equipment

both internal overvoltage and atmospheric overvoltage are higher than 10. The chain may cause flashover of weak insulation points and insulation loss of electrical equipment. In addition, ordinary computers can also be equipped to break down or even burn down
