When I was in the generator business we had a separate department that did thermal imaging of electrical systems.
When you get into big distribution gear, the conductors are large copper bars. These are bolted together for both mechanical and electrical connections. If the bolts become loose, which can happen due to thermal stress, the resistance of the connections can become high enough to cause heating and in a worst case scenario, a fire. Distribution gear would be scanned every few years or spot checks done at the joints to look for localized heating, when if found, would trigger a full blown scan. This department used a very expensive ($50k+) thermal imaging camera to scan the bars under load and record the findings. While we didn't get to play with it, the operators would often have it out of the case and set up on a large tripod in the office, ostensibly to "calibrate" it. What they didn't mention was that they enjoyed watching employees walk by it so they could scan you....
