Performance of High Voltage Switch Tester
Time: Inherent opening and closing time of 12 break contacts, simultaneity within the same phase and between phases.
Reclosing: The closing-opening, opening-closing, and opening-closing-opening process times for each break: first opening time, first closing time, second closing time, metal short-circuit time, and no-current time values.
Bounce: Closing bounce time, bounce count, bounce process, and bounce waveform for each break; opening rebound amplitude for each break.
Speed: Speed at the moment of opening and closing, maximum speed, and time-travel characteristic curve.
Travel: Total travel, open distance, overtravel, overshoot travel, and rebound amplitude.
Current: Opening and closing coil current values and current waveform diagrams.
Operating Voltage: The built-in DC30~250V/20A digitally adjustable circuit breaker operating power supply automatically completes the low-voltage operation test of the circuit breaker and measures the operating voltage value.
