>Suitable for mechanical dynamic characteristic testing of various high-voltage circuit breakers within 500KV voltage level
>Can measure actual stroke and custom stroke
>Can perform single close, single open, close-open, reclose, and reopen operations of circuit breakers
>Convenient wiring and simple operation; only one close (open) action is needed to obtain all close (open) data; can save up to 50 sets of data for later query and upload to computer for permanent storage; can also view and print all data and motion curves on-site
>Built-in clock circuit displays current year, month, day, hour, minute, second; even after power failure, it can automatically save settings and test data
>Built-in delay protection function automatically cuts off the action power after the circuit breaker operates, effectively protecting the circuit breaker equipment and the high-voltage switch tester
>Built-in DC power supply with selectable range: 30-270V/10A; no voltage drop at the moment of output like conventional rectifier power supplies, making it very accurate for testing switch action voltage
>Can dynamically analyze the relationship between stroke and speed of the circuit breaker every 1ms
>Can be configured with upload software for computer archiving and online viewing and printing.
