Thermal imaging is a widely used method as it can identify problems that the naked eye can’t, and it is non-invasive or intrusive. Thermal
imaging can detect potential problems within the electrical distribution system without the need to isolate circuits. Images can be taken of critical components captured in a thermal image and a digital image. Thermal imaging gives you the ability to carry out live testing while meeting your obligations under legislation.
Many potential electrical faults generate excessive heat, e.g. faulty components and loose, oxidised or corroded connections. Thermal imaging can be used to detect these as hot spots.
The technique is particularly valuable where plant breakdown would critically affect business, e.g. a computer centre or food manufacturer. At a more general level, many office power distribution systems are becoming more critical, with greater reliance being placed on
computers. This should increase the benefits (and use) of the technique in the future.
