Preventative/predictive maintenance (PPM) programs are the best way to manage electrical systems.
The National Fire Protection Association (NFPA) 70B §11.17.5 suggests that every commercial and industrial building in the United States should have an IR survey at least once a year. Increasingly, insurance companies are requiring IR surveys of electrical and mechanical systems for their insured. Some companies may even offer discounts if you do.
Widely used application of infrared thermography is most popular. No other commercial application has achieved the level of interest than that of electrical infrared thermography. IR and Electric Inspections go together like milk and cookies.
