Thermal Imaging is a powerful and non-invasive tool for monitoring and diagnosing the condition of electrical installations.

Thermal imaging cameras for industrial applications are powerful and non-invasive tools for monitoring and diagnosing the condition of electrical and mechanical installations and components. With a thermal imaging camera, you can identify problems early, allowing them to be documented and corrected before becoming more serious and more costly to repair.

A thermal image that includes accurate temperature data provides important information about the condition of the inspected equipment. Thermal imaging has demonstrated its ability to detect potential electrical faults, so enabling remedial work to be carried out and failure prevented. However, safety considerations and other constraints which can reduce its effectiveness can limit the implementation of thermal imaging. 

Principles of Thermal Imaging

The radiation emitted from the surface of an object is a function of the object temperature as described by the Stefan-Boltzmann relationship. The infrared element of the radiation is measured and converted into an equivalent temperature. The thermal image is constructed from a multitude of point measurements taken in sequence whilst scanning the field of view, by representing the point temperature values on a grey or colour scale. Single point infrared measurement devices (radiometers) are also available which give an average temperature value for a target measurement area.
