HV Test Services: Sub Station and Circuit Breaker Testing , Speed/ Timing Tests
The time it takes for the breaker to move from a fully closed to a fully open, or open to close is measured in milliseconds
The measured time periods is then compared to the times specified by the OEM
Breakers that fall inside these timing windows and corresponding tolerances, is assumed to be working correctly
Typical opening times could be 20 – 25 milliseconds, while closing times of 50 – 60 milliseconds would be more the average
But these Pass/Fail values has to be taken from the specification as released by the OEM
