13.8kV Test Cabinet
13.8kV Test Cabinet
(OP)
We proposed to provide wall-mounted circuit breaker test cabinet for the 13.8kV switchgear. Our client informed us that they don't require it because they can test the circuit breaker at "test" position at the switchgear.
I think something is missed out here and I wish to seek technical opinion on this.
Thanks

Just this week we were called in to investigate a 38kV metal-clad breaker that "had a bad close coil" and was taken out of service. It would have been a simple matter to confirm or deny had there been a basic test stand. There was an umbilical, but no empty cell to use the test position. Standard troubleshooting determined the coils were all good. But we had to jury rig something to confirm proper electric operation.
If it was my equipment I would provide every opportunity so as NOT to have people "jury rigging" to confirm proper electrical operation. Basic test stands are not expensive and get used often (in my little world at least).
