Early identification of problems is a key aspect of electrical maintenance. For instance, should a back-up generator sit idle until needed, it may not start due to a number of factors. Old fuel clogging a fuel filter, uncharged starting batteries, or start switches left in the wrong mode can all prevent a smooth transition to backup power. These are basic problems, easily identified and addressed through preventative maintenance.
One of the major challenges to electrical maintenance is the nature of electrical wiring. It can be difficult to pinpoint the location of specific problems as the system is built into the building. Thermal imaging has become increasingly important in the industry for its ability to identify issues with both electrical connection points and equipment operation. By catching such problems early, electrical maintenance helps reduce unexpected power outages and protects equipment from damage.
