What is Thermography?

Thermography is the science of measuring and mapping surface temperatures.

How does it work?

An Infrared Thermography scanning device measures and views temperature differences as small as a few hundredths of a degree Celsius. It typically looks for “hot spots” in electrical equipment which illustrates high resistance areas in electrical circuits.

The equipment is portable and only a qualified and experienced Thermographer does the scans on site. In fact, Allan Gibson has more than 20 years of experience in the field.

Why should it be done?

Electrical panels and switchgear supply electricity throughout commercial, manufacturing and industrial buildings.

Infrared is proven to identify electrical problems before their failure. This allows our clients to take proactive steps in preventing a loss of production that may be costly and sometimes even dangerous.

Infrared thermographic testing may be performed during the day or night. It depends on the environmental conditions and the desired results. It also depends on the operating times of the specific industry.

How often should it be done?

Such testing is accurate, economical, does not inconvenience the public and may be repeated.

In fact, infrared scans need to take place yearly for updated results and continuous maintenance. In extreme cases, 6 monthly scans are recommended. 


Prompt reporting allows the client to start maintenance within twenty four hours of the completed scan. We use colour infrared photographic images. These describe the fault and the location in an easy to read document. The fault temperature is also measured and indicated.
