High Voltage Circuit Breaker Factory Acceptance Tests and Inspections

High Voltage Circuit Breaker Factory Acceptance Tests and Inspections

(OP)
Hello,

We are quite familiar with the transformer factory acceptance tests, but know very little about high voltage circuit breaker's.

Anyone can provide such information? If you have the source document, that will be really good.

RE: High Voltage Circuit Breaker Factory Acceptance Tests and Inspections

What type of breaker? By HV you mean >69kV?

RE: High Voltage Circuit Breaker Factory Acceptance Tests and Inspections

Zogzog,

In the IEC world 'HV' means greater than 1000V AC or 1500V DC. The old MV term isn't recognised, not by IEC anyway.

RE: High Voltage Circuit Breaker Factory Acceptance Tests and Inspections

Still depends on breaker type. 5kV air breaker and 230kV GCB are different animals.

RE: High Voltage Circuit Breaker Factory Acceptance Tests and Inspections

Yes, agreed - without more information it's a meaningless question. And if the OP really is asking this question at such a basic level then he / she shouldn't be responsible for witnessing the tests.

RE: High Voltage Circuit Breaker Factory Acceptance Tests and Inspections

(OP)
Thank for all responses. Breakers I am discussing here are 100kV-230kV, OCB or SF6 insulation type...Thanks

RE: High Voltage Circuit Breaker Factory Acceptance Tests and Inspections

I hope that nobody's still building OCBs.

RE: High Voltage Circuit Breaker Factory Acceptance Tests and Inspections

(OP)
Thank you for the reminding. Yes, please exclude the OCB, SF6 only.
