We used an IR scope to find all sorts of trouble spots. Nice tool for drumming up work. It also could possibly save your life. I was on a job in an existing plant where a bus duct elbow fiting finally went phase-to-phase and blew up. That hot spot could have been discovered months before. Now, whenever I am in an area with lots of overhead bus duct, I spook myself wondering if any of the connections were installed wrong and a short might occur. I'd feel a lot safer if I could scope my work area for hot spots.
