Abstract: Introduction was made to the standard and time sequence of site AC voltage withstand test of 750kV circuit breakers. Analysis was made to the test methods based on serial resonance principle and actual parameters of different equipment in test system. On the basis of this, the site AC voltage withstand test system of a set of 750kV circuit breakers was disposed. The actual example shows that the AC voltage withstand test for the main circuit and breaking outlet of 750kV circuit breakers could be completed successfully.
Key words: circuit breaker; AC voltage withstand; quality factor; serial
