Why get a Thermal Survey?

Electrical thermal imaging is the use of thermal imaging to examine the operating temperatures of electrical equipment under normal load. Thermal imaging can be carried out on Low voltage (up to 415V) and High voltage (above 415 Volts) boards including:

  • Switchboards
  • Mechanical services boards
  • Sub-boards
  • Power factor correction units
  • Fuse-panels
  • Control panels
The operating temperatures of in use electrical parts are compared to similar parts to find thermal hot spots (exceptions) such as:
  • Loose Terminations
  • Poor Terminations
  • Rust & Degradation
  • Unbalanced Loads
  • Malfunctioning Equipment

The majority of these problems cannot be detected with the naked eye and instead can be seen through the use of a thermal scanner.

Finding these problems early can have a significant effect on cost and down time of services through:

  • Planning down time for repairs during non-peak times
  • Identify overloaded circuits or under rated cables,
  • Reduce cost of repairs by only replacing faulty components
  • Minimising the risk of fire & damage due to failure of components
  • Ensuring longevity of components through balanced loads.

Electrical thermal imaging is a critical non-destructive testing service for all business owners, business managers, site managers and body corporates.

Thermal imaging of electrical components should be carried out on a regular basis (annually) as a part of a preventative maintenance regime to assess and ensure the health of all electrical systems, furthermore it can potentially be required to obtain insurance or to minimise insurance premiums. During thermal Scanning all equipment must be active and under normal load conditions to be scanned.

Thermal Scanners will provide help in understanding the requirements and benefits offered by utilising electrical thermal imaging. As part of the service Thermal Scanners will provide a detailed insurance compliant thermal report which includes:

  • Detailed scope of works,
  • Thermal and visual images of all Exceptions found including:
    • Location
    • Date and time
    • Priority rating (for level of importance)
    • Possible causes (i.e. Loose connection or Unbalanced Load)
  • Qualification of thermographer

In addition, Thermal Scanners can complete RCD testing during the thermal inspection to save time and cost. Enquire today
