Thermographic Survey

Thermographic Survey

The Thermographic survey of Electrical distribution systems & components is currently the most established survey undertaken. These surveys are non-invasive, relatively quick to carry out, cost-effective and can form part of any predictive maintenance strategy.

Electrical components such as connections, joints and contacts are subject to deterioration over time due to corrosion, loosening, over tightening, contamination and overloading, all of which causes an increase in electrical resistance and subsequently an increase in temperature. If left, further deterioration occurs, resulting in possible equipment failure, fire and even explosions.


Carrying out regular Thermographic surveys results in your Electrical distribution systems and components being evaluated, and any maintenance intervention can be scheduled as part of a predictive maintenance strategy.


We, therefore, recommend regular thermographic surveys of the following types of equipment:

  • Fuse boards
  • Distribution boards
  • Equipment control panels
  • PLC systems
  • Motor control centres
  • High & Low primary voltage systems
  • Electrical switchgear
  • Bus-bar systems
  • Transformers
  • UPS and battery systems


The survey is carried out by a Level II thermographer, and a report is produced giving comprehensive details of all the items surveyed, highlighting faults and advising on the most effective solution.
