Thermographic Testing

 

Infrared Thermography Testing

After an inspection a report will be generated which provides complete documentation of thermal patterns detected in your equipment, structure or system. Its uses a subjective evaluation to help you prioritize repairs to provide the greatest return from this inspection and your maintenance.

The report of infrared inspection meets the documentation requirements of the Infraspection Institute Standard for infrared inspection of electrical systems and rotating equipment, as well as standards, practices and specifications published by ASTM, NFPA and NETA.

How Infrared Thermography Works

Infrared imagers “see” the heat radiated from your equipment in real time, just like a video camera sees visible light. In black and white thermograms (pictures of heat), white is hot and black is cold unless stated otherwise.  When thermograms are in colour, colours in the scene are matched to the reference bar. Colours appearing closer to the top or right of the reference bar indicate higher temperatures. Colours appearing to the bottom or left of the reference bar indicate lower temperatures.

Repair Priority Ratings

Each thermogram is given a Subjective Repair Priority Rating, which is based upon your qualified assistant’s opinion of how critical the subject item is to the safe and profitable operation of your overall system.

Infraspection summary section of this report explains how to use this Subjective Repair Priority Rating to help you determine how quickly you need to investigate and correct the potential problem.

Overheating can cause premature deterioration and costly, unplanned failure of your equipment.

Overheating connectors, conductors and components will never get better. In fact, the temperature and rate of deterioration will increase with time. No one can predict when the failure will occur. As a result, we suggest that you use the subjective Repair Priority Ratings as a guide, and that you investigate and action appropriate corrective measures as soon as possible.

The cost of breakdowns, fire and catastrophic failure to you or your business can be very expensive due to lost productivity and materials. Get your equipment tested now and avoid any potential future breakdowns!
