Thermographic Surveys

Electrical Systems Thermographic Surveys

Thermal imaging is an extremely useful tool for electrical fault finding. It requires no contact being made with the components which means that the components can be checked in a live state with little danger to the user, there is no effect on the components or interruption in any processes the electrical system may be controlling.
Electrical faults can lead to breakdowns and the potential for fire hazards. In both cases the losses due to downtime and repair costs can become costly.
Electrical equipment can suffer from numerous faults which will show an increase in temperature.

For example;

Corroded or loose connections
Imbalanced Loads
Using underrated equipment or overloading equipment
Insulation Damage
Incorrect voltage
Blocked or poorly ventilated equipment
Deterioration due to age
Exceeding the recommended temperature rating

To carry out a survey circuits should be operated at full working load to ensure the highest operating temperature is measured and the full extent of any faults can be seen.
The thermographer will use his knowledge of the components in question and compare them to similar components operating under the same conditions to determine the extent of any faults.

A typical survey of electrical equipment might include:

 

  • Motors and motor control panels

  • Control equipment

  • Cable runs

  • Substations

  • Transformers

  • Circuit operating devices

  • Thyristor banks

  • Switches, fuses and circuit breakers

  • Distribution boards

We will provide the full thermographic survey to the highest of standards as well as providing the complete certification and paperwork that is included with the service.
