1.GDGK-303 circuit breaker analyzer is designed to meet the need of testing high_voltage switches . 

2.It takes the micro controller unit(MCU) for core to sample, process and then output; the main characteristic is that it’s operated in Chinese, for example ,the results are displayed and printed in Chinese. 

3.It has many advantages such as intelligence, multi-function, accurate data, strong anti-jamming, easy operation, small size, beautiful appearance, etc; 

4.It can test the switches as follows:indoors or outdoors switches with less oil or more oil,vacuum switches, SF6 switches and so on. 


Features:

1.Closing and opening time measurement of 12 channels 

2.Max difference of closing or opening time measurement of three phases 

3.Bounce time and frequency measurement of breaker closing 

4.Circuit breaker closing and opening speed measurement 

5.Travel-time, Coil current-time curve of circuit breaker operation measurement 
Clearance of circuit breaker measurement 

6.Variable DC circuit breaker operation power supply 

7.Print test results by internal micro printers
