Electrical systems are the most critical infrastructure within office buildings and industrial applications. Thermography is a method of inspecting electrical equipment by obtaining heat distribution pictures. This inspection method is based on the fact that most components in a system show an increase in temperature when malfunctioning. The increase in temperature in an electrical circuit could be due to loose connections. By observing the heat patterns in operational system components, faults can be located and their seriousness evaluated. The inspection tool used by Thermographer is the Thermal Imager. These are sophisticated devices which measure the natural emissions of infrared radiation from a heated object and produce a thermal picture. As physical contact with the system is not required, inspections can be made under full operational conditions resulting in no loss of production or downtime.The thermography inspection is designed for plant condition monitoring and preventative maintenance of electrical equipment’s. The outcome of the IR Thermography report will itself highlight the problem areas and corrective measures can be carried out by the maintenance staff to avoid any electrical mishaps in the future. The thermography service in India is increasing day by day which results the positive output of increase in production.
