HDKC-12G Circuit Breaker Tester


HDKC-12G Circuit Breaker Tester

 

HDKC-12G Circuit Breaker Tester is applied to accurately test the dynamic characteristics parameter of high voltage circuit breaker such as Oil circuit breaker (bulk-oil-volume breaker, low oil circuit breaker), SF6 circuit breaker, vacuum circuit breaker. It is an ideal test equipment for test circuit breaker at large power companies, which is easy to connect and operate for testing.

 

Feature

 

● Automatically identity open and close status avoiding error operation .

● With 12 independent fractures, it is easy to inspect the connection,  detect and tip the state of fractures .

● Record 100 groups measurement data.

● 7 inchLCD with menu interface, it is easy operation .

● Powerful graphical analysis function to display wave and measurement data

machine integrated operation power supply, no site secondary power, easy to use. Can      provide DC20 ~ 270V adjustable power supply, current 20A.

● Equipped with linear sensor, 360 degrees without dead Angle rotation sensor, with special fixed multifunctional joint. Itis easy and convenient for installation.

● Internalanti-interference circuit can be used reliably in 500KV substation.

● Udisk interface and R232 interface
