The use of infrared viewing systems in electrical control equipment

The use of infrared imaging devices for monitoring the health of electrical equipment is well known and widely accepted in today's industry. Millions of dollars are saved each year in reduced unscheduled downtime and lower capital costs relating to repair of failed equipment. Due to the physics involved in the transmission of infrared radiation, tradition IR scanning methodology involved the removal of outer doors and covers of the energized equipment to provide a direct line of sight to target. With the widespread adoption of NFPA70E and the recent OSHA CFR29 requirements, the exposure of personnel to live electrical equipment is no longer acceptable. This paper explores the difficulties presented to today's infrared maintenance personnel with regard to electrical equipment. The paper presents options for the use of infrared viewing systems and techniques designed to make infrared predictive maintenance faster, safer and more cost effective
