This article describes how to identify problems within the electrical distribution system, both when trouble has already hit and in advance, through routine preventive maintenance. Basic how-tos: Electrical load, safety, and emissivity Today’s thermal imagers are rugged, easy to use, and much more affordable than even just a few years ago. That’s making them a…

Infrared Surveys
Electrical Infrared Inspection Today's electrical systems are complex and high performance. Excessive heat relative to the entire system can be a sign of potential problems. These higher temperatures often indicated loose or faulty connections, improper wiring installation, ground faults, short circuits, and other common electric equipment problems. It is often difficult to determine if there…

Should You Be Doing Electrical Preventive Maintenance? You Bet!
Preventive maintenance is not a new concept. People have been doing precautionary work on motors, engines, and other mechanical systems for decades. But when I suggest doing preventive maintenance on electrical distribution systems, I am often met with incredulous looks and the repeated question, "What for? Nothing moves — what could go wrong?" Preventing Electrical…

Electrical Preventative Maintenance
Too many people mistakenly think a lack of moving parts means little can go wrong with electrical systems. In fact, the Institute of Electrical and Electronics Engineers (IEEE) reports that the failure rate of electrical components is three times higher for systems without preventive maintenance programs. The two top causes of electrical distribution failures —…
