GDGK-307 Circuit Breaker Analyzer
Brief Introduction:
GDGK-307 is designed as per ICE62271 and GB1984, which is used to test the mechanical properties of circuit breaker. It has features of light weight, easy-operation and high precision. It is very suitable to do fast determination on site.
Functi***:
1. Closing and opening time measurement of 12 channels.
2. 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 freqency measurement of breaker closing.
6. Circuit breaker closing and opening peed measurement.
7. Tr***el-time, coil current-time curve of circuit breaker operation measurement
8. Tr***el 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 printer.
