Study on the Invading Wave's Over-voltage Monitoring in Substation

This paper introduces the basic principles of the invading wave＇s over-voltage monitoring devices in the substation,and connecting with the comparison of the field measured waveform with simulating waveform,puts forward a method for realizing busbar＇s over-voltage monitoring by using CVT loop current of CVT on substation＇s busbar,which provides rich,solid and scientific method support for the scientific workers who are researching the mechanism of the generation of over-voltage in power system,the prevention of over-voltage,and the insulation matching of electrical equipment.
