Infrared scan of electrical equipment


Thread Starter

I have had electrical equipment scanned for hot spots. Two different vendors gave me different temperature standards for the urgency of repair.
Can someone provide an independent source or standard from which I can judge the scan results myself?
It has been my experience that overall temperature does not matter nearly as much as temperature difference! i.e. One leg of 3 phase hotter (or colder) than the other two. We have our plant done yearly and the results (using temp diff) were amazing.. All points that were put in the report were then inspected by me, and in every case I DID find a problem with the equipment. You would be suprised to see just how many loose connections there are in a typical plant.. :)
