Thermographic Survey

A thermographic survey (sometimes referred to as a thermography survey or thermal imaging) uses a powerful infrared camera to identify potential dangers in electric equipment.

Electrical parts that are damaged or have loose connections will give off heat which the camera will be able to pick up.

Example of thermal imaging

A thermographic survey is a great option for places like schools, hospitals and prisons as you do not have to switch off your systems or isolate the power while the test is taking place.

We carry out a full thermographic survey to identify potential dangers, providing a comprehensive report and recommendations so you’re not left worrying about what to do next.

Frequently asked questions about thermal imaging (thermographic surveys)

What is thermal imaging?

Thermal imaging is when an Infrared (IR) camera is used to take photos.

Infrared cameras identify heat. The more heat that comes off an object or a person, the brighter the colours that appear.

Thermal imaging can be used to solve a range of different issues. For example, IR cameras can be used to see where homes and buildings are losing energy through gaps in the walls or floors. It can also be used to identify electrical faults.

However, we’re most interested in using IR cameras to identify electrical faults

How can thermal imaging be used to identify electrical faults?

Thermal imaging can identify faulty electrical installations before they stop working, saving time and money

Issues thermal imaging can spot include:

  • Overheating cables or motors
  • Loose, worn and corroded connections
  • Damage and wear to electrical insulation
  • Overloaded fuses and blown fuses (interestingly, blown fuses will be cooler than usual and show up blue)
  • Damp and mould

Where is electrical thermal imaging used?

Thermal imaging is commonly used in places where turning off the power to test equipment will pose a health & safety risk or cause disruption. For example, hospitals, universities, laboratories and prisons.

Can thermal imaging be used alongside EICR?

Yes! Thermal imaging is often used alongside EICR (fixed wire testing) to thoroughly test buildings.

If an electrical installation cannot be turned off (for example, a circuit board in a factory), thermal imaging can be used to test it without having to shut the power down.
