Abstract

Aiming at the present situation that the overvoltage test of the voltage transformer for GIS is very difficult to implement under high voltage

a nanosecond impulse voltage generator with fully-shielded structure is designed.Specific parameters of the impulse voltage generator are given according to its technical requirements.The overvoltage of 110 kV voltage transformer and the factors influencing the overvoltage are investigated experimentally.This impulse voltage generator is suitable for the overvoltage test of the voltage/current transformer for GIS of 1 000 kV or lower voltage classes

meets the requirements of class B surge test

and effectively makes the overvoltage test of the voltage transformer for GIS can be performed under high voltage.
