>Suitable for mechanical dynamic characteristics testing of various high-voltage circuit breakers within 500KV voltage level
>Can measure actual stroke and custom stroke
>Can realize 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 choose to save 50 sets of data, provide later query and upload to computer for permanent storage, and can also view and print all data and motion curves on-site
>Built-in clock circuit can display current year, month, day, hour, minute, second; even after power failure, it can automatically save setting data and test data
>Built-in delay protection function: after the circuit breaker operates, it can automatically cut off the action power supply, well protecting the circuit breaker equipment and the high-voltage switch tester
>The instrument has a built-in DC power supply with selectable range: 30-270V/10A, without the voltage drop at the output instant of 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 to achieve computer archiving and online viewing and printing.
