Infrared Thermo graphic scanning is commonly used as a part of the electrical preventive maintenance program. IR scanning can be used easily and safely on energized electrical equipment and apparatus to diagnose electrical problems in their early stages, which can be corrected before they become major problems. IR scanning is more useful when equipment is under full load because certain types of hot spots cannot be detected while the equipment is at partial load or light load. Many people conduct IR scanning inspection before major preventive maintenance shutdown to identify electrical or mechanical faults that can be corrected during shutdown. A latest variety of IR thermographic systems are available with PtA for conducting IR scanning to identify heat related problems in energized power equipment.PtA provided IR scanning services on Switchyard equipment, transformers, motors, generators, etc.
