circuit breaker tester

• GDGK307 High voltage circuit breaker Mechanical Properties Tester is special instrument for power system GIS mechanical properties measuring.

•  The high voltage circuit breaker tester takes IPC for the core to sample and data process.

•  It has 12.1 LCD to display and 12.1 touch pad for operation. 

• Rich experience database makes the tester more intelligence. 

• The tester has the characteristic of accurate test data, strong antijamming, easy operation, small size and light weight.
