Ⅰ. Introduction
» GDGK-303 Circuit Breaker Mechanical Characteristic Tester is special instrument for power system GIS mechanical properties measuring. The instrument takes ARM7 for the core to process the test data. With high intelligence, lots of functions, accurate test data, strong anti-jamming, easy operation, small size, light weight and so on,
» GDGK-303 Vacuum Circuit Breaker Tester is applicable to kinds of GIS mechanical properties measuring such as indoors or outdoors switches with less oil or more oil, vacuum switches, sulfur hexafluoride switches and so on.
