Principle of frequency modulation series resonance withstand voltage test set in GIS test: GIS is a combination of circuit breakers, isolating switches, voltage transformers, current transformers, arresters, etc., and is insulated by SF6 gas. GIS is generally 2 -18 intervals, each interval in the test is equivalent to a capacitor. The voltage withstand test of GIS is equivalent to the withstand voltage test of this capacitor.
