The objective of a thermographic survey carried out by our trained engineers is to identify abnormally high temperatures within electrical distribution systems. Any high temperatures are often indicative of an imminent or possible problem. Early identification of these faults is essential in order that corrective action can be undertaken before the problem escalates. Electrical circuits and components often fail because of fatigue, defective components, contamination, or just loose connections due to poor workmanship, all have one thing in common, they will always have a rise in temperature or ‘hot spot’ prior to failure.
It is imperative that as many circuits as possible are in operation when we carry out the thermographic survey as it is only when the electrical system is under load, that weaknesses (hot spots) are most readily identified.
Thermographic surveys are particularly valuable on large commercial or industrial sites, where electrical equipment cannot easily be switched off due to interruption in production.
