DESCRIPTION

1) GKC433D circuit breaker analyzer provides timing and motion testing of all types circuit breakers. With reliable and accurate test results even in noisy high voltage substations.

2) Tests all types of circuit breakers, such as LV, HV, EHV AND UHV for all parameters in one time connection.

3) Measures main and PIR contact times, bounce, non simultaneity of contacts and auxiliary contact timings.

4) Analyze contact travel characteristics for speed, insertion, overtravel and rebound with analog transducers or digital transducers.

5) Measure trip and close coil current curve.

6) Display test settings, graphical and test results.

7) Built-in thermal printer, print test result.

8) Connect to circuit breaker with resistant test of enough length.

9) Built-in DC power supply for circuit breaker trip and close pulse.

10) Provide with in-built memory to store up to 500 records.

11) Windows software for further analysis and storage.

12) Circuit breaker analyzer can be operated stand-alone or computer controlled.
