Low-resolution infrared (IR) cameras offer a superior alternative technically and economically for a permanent thermal monitoring of critical components in electrical assets. Therefore, a mapping proce-dure is developed for the combination of an IR and a visual USB camera which delivers a detail-accurate overlay of the thermal on the visible light image representing the so-called enhanced thermal image. The enhanced thermal images support the compartment as well as the component recognition in electrical assets showing the temperatures of regions of interest. Finally, combined with the devel-oped correction algorithm for low-resolution IR cameras, temperature features of those regions of in-terest can be easily extracted for the condition monitoring of electrical assets, such as maxi-mal/minimal, average and environment temperature.
