The circuit breaker tester under UHV power can help many power workers conduct various power tests more conveniently.

1. Time: The inherent opening and closing time of 12 fracture surfaces, same phase and same period, and phase to phase and same period

2. Recloser: The closing closing, opening closing, and opening closing opening of each section of the circuit breaker tester; Process time: One minute time, One in time, Two in time, Gold short time, No current time value

3. Bounce: the closing bounce time, bounce frequency, bounce process, and bounce waveform of each fracture; The rebound amplitude of each fracture opening

4. Speed: initial opening and closing speed, maximum speed, time stroke characteristic curve

5. Travel: total travel, opening distance, overtravel, overshoot, rebound amplitude

6. Current: opening and closing current values and waveform diagrams of the opening and closing coils

7. Action voltage: The machine provides a DC30-250V/20A digital adjustable circuit breaker action power supply, which automatically completes the low voltage action test of the circuit breaker and measures the action voltage value of the circuit breaker
