Paper Abstract

Thermographic inspection is an invaluable diagnostic tech-nique for detecting thermal abnormalities indicative of failure mechanisms in current-carrying equipment. No other maintenance procedure can provide such fast and accurate evaluation of the operating condition of electrical apparatus. Infrared line scanners and infrared imagers are both used successfully for thermographic inspection surveys. Each system has certain advantages and disadvantages. The Barnes Thermatrace single-line scanner and the AGA Thermovision 750 imager are compared. Periodic thermographic inspection surveys in commercial and industrial plants substantially reduce the frequency of equipment failures and unscheduled power outages. Proper planning and organization increase the efficiency of a survey and reduce the cost. Several ex-amples illustrate some of the types of failure mechanisms frequently encountered.
