Product Description

General Information

HDKC-12 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 at below 500kv station .

Features

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.
320X240 LCD with menu interface, it is easy operation .
Powerful graphical analysis function to display wave and measurement data
It is built-in the delay protection function , which will cut off coil voltage automatically after circuit breaker action to protect the circuit breaker and test instrument. Alone open and close control unit can proceed open test and close test . It will not affect the operate if one of control loop is error .
It can proceed automatic and manual open/close test .
Re-close test, close-open test, open-close test and open-open test
Vacuum contactor( uni-coil)parameter measurement.
Automatic aging test of circuit breaker(lift-time test)
