Circuit Breaker Inspection 525 Kv

What technologies are available to examine (preferably in real time) the internals of large diameter Circuit Breakers: 6mm thk Alum x 1.2m diam cylindrical contruction? The aim is to inspect the internal electrical componentry to determine if damage or deterioration has occurred which could result in unexpected short circuit and failure. Generally the access is difficult and conventional radiography both film based and realtime have proved inconclusive.

Any Suggestions?

Hello there. My company performs Thermography to inspect circuitry in buildings for evidence of overheating. Deterioration at connections would result in a thermal change and are therefore detectable. The circuits would need to be live.

Thanks,
Todd

Re: Circuit Breaker Inspection 525 Kv This is the sort of thickness where eddy current can be usefull. Although your description is some waht vague.

Any chance of sending me a sample of good and bad (a section will do and wee can have a look at it). See our web site www.hocking.com for the address.

Regards

John Hansen
