Abstract :
The dielectric performance of the circuit breaker between poles after current interruption was verified by testing. Test conditions based on IEC standards were examined. Based on these, a synthetic testing circuit with a voltage injection scheme was conceived. For both the 154 kV noneffective grounded system and the 300 kV effective grounded system, a practical testing method was realized
