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

Product Spotlight

Varex Imaging Large Field of View (FOV) Digital Detector Arrays (DDAs)

A larger FOV DDA can reduce the space and volume of the X-ray inspection system on the factory floor
...
, enable faster scanning times, better throughput and better resolution images at a lower dose. Customers can also save time and money. With these benefits in mind, Varex Imaging has designed a family of large FOV detectors (4343HE, XRD 1611, 4343DX-I, 4343CT) for our industrial imaging customers.

FMC/TFM

Next generation for Phased Array UT is here now with FMC/TFM! Have higher resolution imaging, impr

oved signal to noise ratio, characterize, size and analyze defects better with access to several wave mode views and save raw FMC data for higher quality analysis.  Some of the benefits are:
  • Beautiful Image! Easier to understand what you're looking at
  • Completely focused in entire image or volume
  • Much easier to define setups before inspection
  • Easier to decipher geometry echoes from real defects
  • Oriented defects (e.g. cracks) are imaged better
  • See image from different wave modes from one FMC inspection
  • FMC data can be reprocessed/analyzed without going back to the field
