Thermal Imaging

What is Thermal Imaging?

Thermal Imaging, also known as thermography, is the production of infrared or heat pictures which can pick up images which are often invisible to the naked eye. Potential problems are highlighted where there is an excess of heat being released by a component, which if left undetected can result in failure and in extreme cases fire.

Thermal Imaging can detect:

Loose connections Overloads Phase imbalances Blocked or restricted cooling tubes in transformers High resistance in fuses and switchgear. Thermal imaging should not be used as an alternative to a fixed wire inspection but be used in conjunction with it as it is limited in its ability to detect all electrical faults.

Why do we need to carry out Thermal Imaging?

The Electricity at Work Regulations 1989 places a duty of care on employers to maintain electrical systems to prevent danger where otherwise it may exist. Thermal Imaging can be a valuable tool as it highlights any potential causes for concern without the need to isolate circuits. This allows corrective action to be taken before any costly system failures.

Who should carry out the work?

Thermal Imaging should be carried out by a fully qualified and experienced test engineer, such as a fully qualified electrician who has experience of test and inspection and has been trained and qualified in electrical inspection work specifically.

Survey Report

Within a 72 hours of a survey being carried out we will produce a full report documenting all of our findings. This will include:
  • Reference to building drawings/plans
  • Camera serial number, time and date of survey
  • Environmental Conditions of Survey
  • Locations of where the still IR images were collected
  • Qualitative infrared and digital images
  • Report pages detailing observed anomalies with analysis
  • Date, signature, calibration certificate of camera and Thermographers certification number.

Thermal Imaging Surveys

There can be many occasions when building performance survey would be beneficial to a homeowner. Below are just a few:
  • Pre-purchase of a new property.
  • Selling of an old property
  • Throughout construction phases
  • Quality assurance of completed work
  • Compliance with insurance requirements
  • Flood damage assessment
  • Improvements to your homes comfort and efficiency.
