Overview

Thermographic surveys use a thermal imaging camera to identify unusually high temperatures within an electrical distribution system that may cause risk. They are a useful way of testing electrical installations without disrupting essential power supply.

The survey will verify (as far as is reasonably practicable) that installations show no signs of overheating or overload and can detect potential problems that a visual inspection alone will not identify.

The benefits of performing a thermographic survey are recognised within the industry and can support your periodic inspection and testing regime.
During this service, one of our competent inspectors will conduct a thorough visual inspection and thermographic survey of electrical installations (where practicable), examining:

  1. Safety
  2. Wear and tear
  3. Corrosion
  4. Damage
  5. Excessive loading (overloading)
  6. External influences
  7. Suitability

Visual Inspection of items subject to a thermographic survey

We can conduct a visual inspection of electrical installations, including but not limited to, an internal inspection of all accessible distribution, bus‐bar chambers and distribution boards to consist of the following, but only those subject to a thermographic survey:

  • Joints and connections
  • Conductors
  • Flexible cables and cords

Reporting

At the end of the inspection, you will receive a report highlighting any defects that have been found.

When a temperature difference of 15oC between similar components is found, or when a temperature difference between a component and ambient air exceeds 40oC, then a Code 1 will be raised (Danger Present - The safety of those using the installation is at risk). This will be notified to the duty holder or representative immediately.

It is not recommended to substitute a routine maintenance programme with a thermographic survey.

To keep track of your compliance, our web portal provides online access to your reports completed by Centrica Business Solutions. It shows your overall site compliance and any areas that have been highlighted for remedial action, as well as notifications for renewals.
