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. Infrare ....etc

Infrared and thermal imaging is a global area inspection technique that detects and measures temperature and temperature differences to detect indication of disbond, delamination, cracks, residual stress and other conditions that impact heat flow. IR images provides temperature maps. Thermography is the use of IR imaging and measurement camera to see and measure thermal energy. Thus thermography measures heat which is constantly radiating away from any surface. This method is attractive for diagnosis because of its safe and non-invasive nature. ....etc
