In the power system, various voltage grades of power distribution line, generator, transformer primary switching device, etc., can only withstand its rated voltage in normal operation. However, in the abnormal case, it may be far more than the rated value due to some reason, the main insulation of the above electrical equipment is far more than the rated value, although the time is very short (generally from a few microd to tens of milliseconds), but the voltage The raised value may be large. When there is no protective measures or equipment itself, the device is destroyed to cause damage to the normal operation of the power system. Basic production of this voltage that is dangerous to insulate the equipment is overlapping the voltage.
