High Voltage Switch Characteristic Comprehensive Tester

2. Product Features:

  1. Time: Inherent opening and closing time for 12 break contacts, same-phase synchronization, and inter-phase synchronization.

  2. Reclosing: For each break contact, the close-open, open-close, and open-close-open process times: one-open time, one-close time, two-close time, metal short-circuit time, and no-current time values.

  3. Bounce: For each break contact, the closing bounce time, bounce count, bounce process, bounce waveform; and the opening amplitude for each break contact.

  4. Speed: Just-open and just-close speed, maximum speed, and time-travel characteristic curve.

  5. Travel: Total travel, opening distance, overtravel, overshoot travel, and amplitude.

  6. Current: Closing and opening coil current values and current waveform diagrams.

  7. Operating Voltage: Built-in DC30～250V/20A digitally adjustable circuit breaker operating power supply, automatically completes low-voltage operation tests of the circuit breaker, and measures the operating voltage value of the circuit breaker.
