Infrared thermography has evolved into one of the most valuable diagnostic tools for Predictive Maintenance of electrical equipment from reliability and safety point of view. By detecting anomalies often invisible to the naked eye, thermography allows corrective action to be taken before costly system failures occur or where safety of man and machine are at stake. By utilizing thermography to inspect electrical systems and components under load, the faulty components can be identified and thus heavy loss of health and wealth is avoided. Infrared cameras have become compact systems that look just like a normal video camera is easy to use and generate a real time high resolution image. Numerous industries worldwide have discovered the advantage of incorporating infrared cameras in their predictive maintenance schedule? This seminars gives an indepth account on the basics and its utilization in the field of electrical engineering When considering remote or non-contact diagnostic testing of electrical equipment, infrared thermography is regarded as the most powerful of all diagnostic tools currently available. Of all causes of electrical failures, connection problems are number one. The key method chosen to identify these problems is infrared thermography. An infrared thermographic survey should be performed annually in commercial buildings as well as manufacturing plants. All cable runs, bus ducts, distribution panels, motor control centers etc. should be checked to hotspots or heat imbalances. This can identify loose connections, overloads, unbalanced loads, and high neutral currents that need to be corrected.
