sf6 circuit breaker leak detection for 132kv

Oct 25, 2020The resistance of main circuit is measured from DC voltage drop across the circuit. In this test, direct current is injected to the circuit and corresponding voltage drop is measured and from this resistance of the circuit is measured. The injected current would be from 100 A to maximum rated current of the circuit breaker.The maximum measured value can be 1.2 times the value obtained at
