2.Equipment Description:

HYGK-306A Circuit Breaker Tester is designed to meet the need of onsite test the dynamic characteristics of High-Voltage Circuit Breakers . It takes the ARM7 unit for core to sample, process and output; the main characteristic is that it’s operated in alt. It has many advantages such as intelligence, multi-function, accurate data, strong anti-jamming, easy operation, small size, light weight ,beautiful appearance, etc; It can test the Circuit Breakers as follows: indoors or outdoors Circuit Breakers with less oil or more oil, vacuum Circuit Breakers, SF6 Circuit Breakers and so on.
