The timing of a thermographic survey can determine how much of that effort is wasted. Thus, avoid performing one shortly before a planned shutdown. You want to use that shutdown to fix problems you found during the survey, and some repairs may involve significant lead times. Consider some of the resources:
- Outside contractors. You may need a specialized firm to address those hotspots all over the MCC.
- Spare parts. That replacement 2,000A breaker probably isn't going to be lying around on a shelf. It may even have to be built.
- Special equipment. Renting a special test set on short notice may be doable for an extra fee, but renting a crane on short notice is normally not possible.
