Comment on Infrared Scanning Enclosed Bus Duct and Bus Plugs by MIDWEST

Insulation failure in 480 volt and 208 volt bus duct can be difficult to detect during the incipient stage. We would expect electrical insulation failure to actually be failure over the surface of the insulation and not ‘through’ the insulation. To be caused by contamination or physical breakage of the insulation due to constant vibration or impact or huge load cycling. Failure at ‘through bolts’ might be caused by constant vibration. If the failure was at the end splice plates, one would suspect wrong bolt torque values. It is a challenge to maintenance test bus duct for ‘insulation resistance’ because it is hard to isolate the bus duct proper. If you have a failure, it is important to save the failed equipment and analyze it for ‘failure mode.’ Use this analysis to determine how to avoid possible chronic failures. These are easy words, but hard to do in the real world.

MIDWEST does not sell equipment ‘as is’ to end users, ie individuals, manufacturers, contractors etc. We only sell equipment “as is” to other electrical switchgear service companies that have the ability to properly service the equipment to assure it operates safely and properly. There have been a few exceptions such as requests from Tech Schools for training purposes only.
