In the power system, all kinds of transmission and distribution lines of the teeth.generatorTransformer switching memory device, etc., in the normal operating condition only by its rated voltage. However, in the abnormal case, it may cause the above-mentioned electrical equipment main insulation or the electric voltage of the above-mentioned electrical equipment to be much more than the rated value. Although the time of the river section - (generally from a few subtle to dozens of milliseconds), the voltage The elevated value may be large, and when there is no protection measures or the equipment itself, the equipment is destroyed to make the normal operation of the power system suffer. This voltage is usually transmitted to the voltage to increase the voltage.
