Thermographic Electrical Inspections

Electrical Thermal Imaging – Precision Inspections for Critical Systems

Electrical thermal imaging is an essential tool for detecting overheating components, loose connections, and load imbalances in electrical systems. Our certified thermographers are highly trained to conduct accurate, non-invasive inspections using high-resolution infrared cameras, ensuring early fault detection and preventive maintenance across various industries, including data centers.


We specialize in:

– Data Center Electrical Thermography – Identifying hotspots, failing connections, and power distribution issues in UPS units, PDUs, switchgear, and cooling systems to prevent downtime.

– Industrial & Commercial Facilities – Ensuring compliance, safety, and efficiency with detailed thermal analysis of electrical panels, transformers, and distribution boards.

– BREEAM & Compliance Inspections – Supporting energy efficiency certifications with comprehensive thermal reports for facility management teams.

Our expert engineers ensure all critical object parameters—such as emissivity, ambient temperature, reflected temperature, distance, and humidity—are set accurately before every inspection. This guarantees precise thermographic data for reliable fault diagnosis and maintenance planning.

Using our advanced TICOR reporting modules, we provide detailed thermal reports that enable facility managers to make informed decisions, prevent system failures, and improve energy efficiency. Whether for predictive maintenance or regulatory compliance, our electrical thermal imaging solutions help you protect assets and maintain uninterrupted operations.

What’s Involved In An Electrical Thermal Imaging Survey?

An electrical thermal imaging survey is a non-evasive and non-destructive procedure using infrared technology.

An electrical thermal imaging survey using a thermal imaging camera can be used on different types of equipment including:

  • • Busbar systems
    • Distribution boards and fuse boards
    • High voltage systems
    • Transformers
    • Control panels
    • Batteries
    • UPS systems
    • Switchgears and switchboards

Using infrared technology on electrical infrastructure is a renowned method of predictive maintenance and done correctly it can be effective at fault finding prior to equipment failure but it needs to be carried out correctly. Our strict protocols ensure that the faults we document are indeed items that require investigation and possibly remedial work and not simply loaded circuits manifesting temperature.

All panels removed where acceptable, safe to do so and on the Permit to Work

All electrical equipment/panels/cubicles etc inspected have their own individual trend page which includes a thermogram and digital image, ambient, measured and delta T trending of temperature. Trending compares data automatically between inspections.

The last four thermograms are included on each page and all trend data is captured and displayed in a table and also in graphical format for Measured, Ambient and Delta T (meas/Amb) to allow for condition monitoring of equipment.

Detailed fault pages including Load correction formula is utilised during the inspection.

Using component rating, actual load, measured temp and ambient temp, the following values are produced:

  • • Load corr temp: estimate of component temp if operating at 100% load
      Fault severity based on load corr temp – ref temp (from BS7671)
  •   Estimation of maximum amps to apply whilst keeping temperature beneath reference temp (BS7671)
  • • Visual inspection included to help with your compliance of 17th edition BS7671
      Partial Discharge included (upon request) for high-level overview of PD status
  • • If PD is found we suggest a return visit utilising our Instant report generation which can be emailed to the client at the end of the
      inspection
  • • One-click upload to WEBCOR for instant client access to inspection data
