Introduction:
The High-Voltage Circuit Breakers Analyzer is my company designed to meet the need of testing High-Voltage Circuit Breakers .
It takes the ARM7 unit for core to sample, pr℃ess and then output; the main characteristic is that it's operated in alt.
It has many advantages such as intelligence, multi-function, accurate data, strong anti-jamming, easy operation, small size, beautiful appearance, etc;
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:
Test standard: IEC62271
Closing and opening time measurement of 12 channels
Max difference of closing or opening time measurement of three phases
C-O and O-C time measurement
Rated operation sequence test
Bounce time and frequency measurement of breaker closing
Circuit breaker closing and opening speed measurement
Travel-time, Coil current-time curve of circuit breaker operation measurement
