Detect, Protect, Prevent: Thermal Imaging Solutions for Business Electrical Safety

Thermal imaging, also known as infrared imaging or thermography, is a technology that allows you to capture and visualize the infrared radiation (heat) emitted by objects, people, or animals. Unlike visible light, which the human eye can see, thermal imaging detects and displays the heat energy or temperature variations in the form of a thermal or infrared image.


Here’s how thermal imaging works:


Infrared sensors or cameras: A thermal imaging device contains an infrared sensor or camera that is sensitive to the infrared radiation in the electromagnetic spectrum. These sensors can detect the temperature differences of various objects.


Heat emission: All objects with a temperature above absolute zero (-273.15 degrees Celsius or -459.67 degrees Fahrenheit) emit infrared radiation. The hotter an object is, the more infrared radiation it emits.


Image conversion: The thermal camera converts the detected infrared radiation into a visual image, typically using a colour scale, where different colours or shades represent different temperatures. For example, warmer areas may appear as red or white, while cooler areas may appear as blue or black.


Thermal imaging is a valuable tool for non-contact temperature measurement and identifying anomalies that are not visible to the naked eye, making it useful in a wide range of professional and scientific applications.

We use the state-of-art Thermal Imaging technology to proactively manage your safety

For those years in between Fixed Wire testing, how can you proactively keep on top of the status of your electrical systems?

If you want a way to gather useful information on the performance of your electrics between inspections, then Thermal Imaging may well be the perfect solution.

Thermal Imaging uses thermal cameras to identify problem areas with electrical equipment. Potential problems can often be found due to excess heat being released by an electrical system.


By using Thermal Imaging, we can accurately identify existing faults with your electrical installations. It also helps us to predict any potential issues that may go undetected during routine inspections.

The result for you? A greater peace of mind and the reassurance that you’re being proactive with your compliance.

Our engineers can accurately identify existing faults with an electrical installation, as well as predict potential future issues that could save lives.

By detecting anomalies often invisible to the naked eye, thermography allows corrective action to be taken before costly system failures occur.


Thermal Imaging or Thermography is the process of using a special camera designed to look only for heat by way of infra red (IR) energy waves. Potential problems can often be found due to excess heat being released by an electrical system, even those which would normally produce some heat when performing at their optimum level.


If undetected these problems can lead to failure and can result in expensive production loss or downtime and, in the most extreme case, can lead to fire. A regular programme of thermal imaging as part of routine maintenance can highlight potential problems long before any event. As a result any required repairs can be planned for in terms of both time and budget. In short, it is an invaluable resource for predictive maintenance. Thermography has applications in many different areas which are listed below.
