Abstract: | An important aspect of plant operation is preventive maintenance of electrical apparatus. Local thermal overloads or bad electrical connections often appear as localized hot spots in energized electrical equipment. A survey of the use of infrared detection systems for location of such hot spots is presented. A tutorial introduction to infrared detection and imaging systems is given with emphasis on the requirements imposed by this particular application. Following this, a survey of commercially available systems suitable for remote detection of hot spots is presented. Finally, the highlights of new developments in infrared technology are discussed. |
