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.
