High Voltage Circuit Breaker Factory Acceptance Tests and Inspections

[Beengineer]

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.

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

 

[ScottyUK]

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.

 

[Zogzog]

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

 

[ScottyUK]

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.

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

I hope that nobody's still building OCBs.

 

[Beengineer]

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