Thermal Image Surveying

At Aldridge energy we can provide and carry out a Thermal image surveying assessment in halesworth, Suffolk and surrounding areas also East Anglia.

A thermal imager can save time and money by finding potential problems before they become costly disasters. With thermal imagers you can efficiently inspect an entire facility for hidden issues or monitor a thermal process frame-by-frame.

Thermal Surveying is an unbeatable method for detecting electrical faults and problems before they cause full breakdown of the installation.

Thermographic Surveying (Thermal Imaging)

A useful addition to a preventative maintenance program. Aldridge Energy carry out a thermographic scan of all areas likely to be running too hot or too cold (in the case of failed refrigeration insulation for example). Any areas of the site that register as potential too hot or too cold (be that electrical or mechanical) will be captured as thermal images and photographic images and will be included in the report.

It must however be understood that thermal imaging is not a substitute for Periodic Inspection and Testing. It can however provide a useful interim back up in a maintenance program between formal inspection and testing and can complement the overall system information available to the duty holder.

It can also be very beneficial in situations where access may be restricted or shutdowns to fully test are not possible. Some of our competitors claim thermal imaging to be the be all and end all, but it is not a substitute and it should never be relied upon as the sole means of fault identification in the preventative maintenance program of an electrical systems.

What Thermal Imaging can identify

  • High resistance connections
  • Hot spots
  • Over loaded cables
  • Over loaded fuses or breakers
  • Imminent motor or conveyor bearing failure
  • Motor windings over heating
  • Overheating in distribution equipment
  • Phase load imbalance
  • Hot spots in high level lighting (easily scanned from the floor)
  • Heat build-up in overcrowded trunking
  • Thermal insulation breakdown (hot or cold)
  • Thermal loss
  • Damp ingress

What Thermal Imaging cannot identify

  • Over rated fusing
  • Under rated cables (unless they are over loaded at time of survey)
  • Physically damaged equipment, possibly exposing live parts
  • Lack of earth continuity
  • Undersized earth conductors
  • Prospective fault currents too high
  • Prospective fault currents too low
  • Poor insulation resistance
  • Borrowed neutrals
  • Broken ring mains
  • Lack of RCD protection
  • Protective device cascading of discrimination failures
  • And many more...

Thermal imaging can be carried out on a site-wide basis fairly quickly and cost effectively and is largely unintrusive. However, panels and cabinets will need to be opened in order to scan the components within, this may require a shutdown of the panel to achieve. The thermal imager needs to physically see any hot item to detect it, it cannot see through solid barriers such as doors or cabinets.
