High voltage switch tester/vacuum interrupter tester

Introduction: 

1.GDGK-306 High Voltage Circuit Breaker Tester, HV Switch Tester is designed to meet the need of testing High-Voltage Circuit Breakers . 
2.It takes the ARM7 unit for core to sample, process and then output; the main characteristic is that it`s operated in alt. 
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 Circuit Breakers as follows: indoors or outdoors Circuit Breakers with less oil or more oil, vacuum Circuit Breakers, SF6 Circuit Breakers and so on. 

Features:
1.Test standard: IEC62271 
2.Closing and opening time measurement of 12 channels
Max difference of closing or opening time measurement of three phases
3.C-O and O-C time measurement
4.Rated operation sequence test
5.Bounce time and frequency measurement of breaker closing
6.Circuit breaker closing and opening speed measurement
7.Travel-time, Coil current-time curve of circuit breaker operation measurement
8.Travel and clearance of circuit breaker measurement
9.Variable DC circuit breaker operation power supply
10.Closing arc resistance value and connected time measurement
11.Closing time and opening time of graphite circuit breaker measurement
12.Print test results by internal micro printers
