What is Infrared Scanning?

Infrared scanning identifies the transfer of infrared heat radiation from an object. It provides the means to scan the thermal emissions of various surfaces and display an image of temperature distribution.

The heat signature is identified with the use of an Infrared camera. Infrared scanning is used to confirm machinery is running normally and to detect abnormal heat patterns within a machine, indicating inefficiency and defects. Electrical circuits and components often fail because of fatigue, defective components, contamination, or just loose connections due to poor workmanship, but all failing components have one thing in common, they will always have a rise in temperature or ‘hot spot’ prior to failure. The infrared images of the temperature distribution are called thermograms and they enable us to see heat-producing objects.  The pictures are then analyzed by a certified thermographer and put into a report for industrial electricians. The report will identify areas that have a build-up of heat from any electrical element under stress and allows us to determine whether or not the equipment will fail. InCheck Electric electricians can rectify before a breakdown occurs, preventing loss of production due to unplanned downtime. Early identification of these faults is essential in order that corrective action can be undertaken before the problem escalates.

 

What are the benefits?

The objective of a thermographic survey is to identify abnormally high temperatures within electrical distribution systems. Any high temperatures within electrical components are  often indicative of imminent or possible problems.

Benefits include:

  • Saves money
  • Reduces downtime
  • Increases safety
  • Improves insurability
  • Improves system performance
  • Reduces risk of equipment failure
  • Reduces construction schedule delays
  • Reduces liability exposure of the designers and installers
  • Determines whether components and systems operate properly and meet the design intent
  • Determines if the components and system have been properly installed and are not damaged

The Institution of Engineering and Technology (IET) recognize the benefits of performing thermographic surveys of an electrical distribution system, as a supplement to a periodic inspection and test. It is not however, a substitute for an inspection and test program or documented routine maintenance program.
