Infrared, "Motion Amplification" & Airborne Ultrasound Inspections


Low and Medium Voltages (24vdc - 1000vac)

Infrared electrical inspections find hot spots caused by defects in connections and components. Infrared thermography is used to find areas of excess heat (caused by increased resistance) so that problems can be corrected before a component fails, causing damage to the component, creating safety hazards and productivity loss. Because increased heating is a sign of failure, infrared is the best diagnostic tool available for finding these hot connections in the early stages of degeneration. 

Before an electrical component burns up, it heats up. Infrared thermography is used to perform Pd/Pm inspections on electrical equipment because excess heat is usually the first sign of trouble on low or medium voltage electrical (or mechanical) apparatus. Loose connections, imbalanced circuits, defective breakers, damaged switchgear, faulty fuses or fuse clips, overloaded circuits, material defects and a range of other conditions will eventually lead to excess heat and component failure.


Airborne Ultrasound High Voltage Electrical Inspections

In electrical applications, airborne ultrasound can detect corona which exists above 1 kV and does not generate any heat. Infrared, therefore, can not find the existence of corona which if left unattended will further develop into tracking and arcing situations. Ultrasound analysis provides a more comprehensive electrical inspection when used with infrared to identify corona, tracking, arcing, and resistance problems in any electrical equipment.
