Inspections of electrical installations
Thermography provides a fast overview of the conditions of electrical installations
- Hot-spots ar a good indicator for faults when doing comparative thermography
- Reliable detection of hot-spots requires sufficiently high number of pixels
- During thermographic measurements load conditions have to be kept in mind
- Important flexibility of thermal camera systems is reached by interchangeable lenses
Details about electrical installations
Qualitative thermography allows easy inspections
Inspections of electrical installations mostly focus on the detection of hot-spots – areas with excessive temperatures. Those can often be found by comparison of the same kind of components just having different temperatures. For example one phase can have a higher temperature in comparison with other phases due to a poor insulation which results in a creeping current. Already such a comparative analysis called qualitative thermography is absolutely sufficient in many inspection situations.
Only having a sufficient number of pixels faults can be identified
To provide a secure conclusion the thermal camera being used needs to come with an adequate resolution. Inspecting electrical installations especially the geometrical resolution should be focused on which is the number of pixels being available for the measurement. The more pixels being available the smaller are the hot-spots which can be detected from a certain distance and the earlier a developing fault can be discovered resulting in a more secure inspection result. Like this no averaging of higher hot-spot temperatures and lower surrounding temperatures is made up which could prevent correct measurements with a thermal camera.
Temperature measurements are influenced by load situation of electrical installations
Very important for thermographic analyses of electrical installations is their load behaviour. When thermographic measurements are done in low load situations hot-spots will not be detectable securely as those areas will appear a lot colder than running at full load. Therefore either the measurements will be done at full load or the measured lower temperatures will be converted to those which would be measured when running at full load.
Interchangeable lenses allow the flexible usage of thermal camera systems
Very often thermography is used for controlling high voltage installations outdoors. To do those measurements correctly measuring smallest details full signal telephoto lenses should be used. In contrast limited space indoors could well result in the need to use wide-angle lenses for coverage of complete switchboards.

Testing of photovoltaic installations with VarioCAM ® high resolution
Based on programs for energy conservation and for promotion of renewable energies, until 2009 in the European Union photovoltaic facilities for more than 15 GWp were installed, which approximately corresponds to the surface of Milan. Like for all electrical devices, solar cells and modules need to be maintained especially as they are located outdoors. Infrared thermography offers the possibility to localize and classify problems fast and also with a high accuracy.
