Thermal Image Testing

United Electrical Testing Services are able to offer Thermal Imaging or Thermography testing for all electrical testing services and installations.

Thermal Imaging electrical testing can detect and locate the following:
? Overheating & overloading of cables, fuses and control equipment. ? High resistances within switchgear and control equipment. ? Arcing or loose connections ? Identify running temperatures of components, plant or machinery. ? Power & phase imbalances.

Thermal Imaging is the process of using a special heat/temperature style camera designed to look only for Infra Red (IR) energy, which is effectively heat energy. Unlike the normal light energy or light waves, Infra-Red energy or heat energy is invisible to the naked eye.

Potential problems can be located very quickly and efficiently and without the needs to isolate any power sources, plant or machinery. Infra-Red heat energy is often released by components, plant or machinery whilst performing at their optimum level and is therefore difficult to ascertain by touch whether a component is running at normal temperature or is in fact overheating, whereas with a thermal image the result are instantaneously and the exact temperature of the component can be measured, thus providing an accurate guide to operating levels.

 

If potential problems are left undetected these can eventually lead to power failure and the resulting expense incurred for lost production and downtime, lost orders and could eventually lead to fire.

As Infra-Red heat cannot be seen, the differences between normal operating temperatures and increased operating temperatures due to possible malfunction or overload could not be detected by hand or eye contact, Thermal Image testing is the ideal choice when carrying out routine maintenance visits and can highlight potential problems long before any event occurs, resulting in preventative maintenance as opposed to reactive maintenance and the resulting costs saving associated with such planned maintenance. Thermal Imaging is a non-contact form of testing and is invaluable for predictive diagnostic maintenance work.
