A voltage rise that jeopardizes the insulation of the device is called an overvoltage. There are two types of overvoltage: operation, short circuit, etc. (1) The overvoltage caused by lightning is called atmospheric overvoltage. (2) The overvoltage caused by internal operation or failure of the power grid is called internal overvoltage.
