Potential problems can often be identified by an excess of heat being released by machine components, (even those which would normally produce some heat when performing at their optimum level). If undetected these problems can lead to failure. These failures can result in expensive production loss or downtime and in the most extreme case can lead to fire. Thermal Imaging or Thermography is the process of using a special camera designed to look only for heat using Infra Red (IR) energy waves. Unlike light waves, IR is invisible to the naked eye and therefore so is heat. This makes Thermography an important part of a routine maintenance schedule. At E3 Electrical we use the latest infrared thermographic equipment to assess high voltage distribution boards, power supplies, transformers and machinery with minimal disruption, highlighting any over loaded components, out of phase power supplies or poor connections. Not only can this thermal imaging help you plan a maintenance schedule, and minimise shut down time, it can also satisfy insurance policy requirements.

Each distribution board can be assessed with just one thermal image and physical contact with the components is not necessary (no down time. IRT turnaround client reports within 3-5 working days and our equipment is state of the art guaranteeing our clients the most accurate information available. A regular programme of Thermal Imaging as part of routine maintenance can highlight potential problems long before any event. As a result any required repairs can be planned for in terms of both time and budget. In electrical systems Thermal Imaging can find:


  • Loose connections
  • Overloads
  • Phase imbalances
  • Blocked or restricted cooling tubes in transformers
  • High resistance in fuses and switchgear
  • Thermal imaging is one of the most valuable diagnostic tools for predictive maintenance
