Thermographic Electrical Inspections

Thermography is a tool for recording nearest surface temperatures and our expert engineers have the ability to correctly set up their cameras with the right object parameters for the given situation. Our high level training ensures that we correctly assess the inspection and apply the required thermographic technique. We will ensure that the correct object parameters are input prior to any inspection commencement including emissivity, ambient and t-refl temperatures, distance, humidity and any other associated values required for accurate thermographic image interpretation. We offer premium grade thermography for any application where there is either a temperature or emissivity differential so that anomalies can be observed and expertly reported on utilising one of our purpose built TICOR modules.

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
