Importance of electrical thermal imaging

Posted: March 14, 2022

Did you know that your electrical systems and equipment could be running at a very high heat level and becoming a potential safety risk? With thermal imaging, our team of qualified electricians can detect faults in your electrical system that aren’t visible to the naked eye. Our advanced thermal imaging equipment allows us to assess the heat signature of electrical systems and spot any faulty equipment that’s running too hot. This means that we can identify possible electrical problems early, avoiding equipment failure and potentially more serious concerns.

What is thermal imaging appliance electrical testing?

Electrical thermal imaging is a non-invasive diagnostic technique that identifies faults that the naked eye can’t see. Using infrared cameras, our certified electricians can visualise and quantify changes in the surface temperature of electrical equipment. The scanner works by converting infrared radiation (heat) emitted from the surface of electrical equipment into electrical impulses, which are mapped as colours that represent the various temperatures. 

To prevent overheating in your switchboard, arrange a thermal imaging electrical inspection tag from Voltec Maintenance and contact us today.


Benefits of thermal scanning for electrical systems – electrical inspection tag

  • Minimise the occurrence of fire caused by electrical faults
  • Reduce the chance of equipment failures
  • Quickly identify potential problems
  • Minimise downtime for the business
  • Accurately identify the site of the issue so repair can be specific and targeted
  • Assists with insurance compliance requirements and reduces insurance premiums
  • Boosts workplace safety measures
  • Issues can be detected and repaired before problems occur

Recommended frequency for thermal imaging 

Before an electrical component burns up, it heats up. Early detection with infrared thermal scanning detects growing problems before they cause a system failure or even an electrical fire. Therefore, thermal imaging should be carried out every 12 months by a qualified electrician, so that any problems can be corrected before the component fails. Furthermore, if your building is situated where environmental factors are prevalent, it is highly recommended that testing should occur more frequently.

How can Voltec Maintenance help? – Thermal imaging specialists

At Voltec Maintenance, we offer routine thermal scanning of electrical switchboards found within the workplace as part of an annual electrical maintenance program. Firstly, our team will inspect your premises using an infrared thermal imaging camera through which we’re able to detect infrared radiation. This allows us to diagnose any potential hazards within an asset’s electrical infrastructure and make recommendations on how to keep that asset functioning safely and effectively. After the initial thermographic survey, our team will provide you with a detailed thermographic inspection report that describes:

  • The specific equipment and switchboards inspected
  • Any areas of concern including failing components
  • The extent of the defect
  • Specific temperature variations recorded
  • Proposal for maintenance required

Unlike when things go wrong, a thermal imaging inspection causes no disruption to your workplace. Inspections can be carried out while the building is operating normally, without the need to disrupt your power supply.

Have you had your building inspected with thermal imaging recently? If it’s been over 12 months since your last inspection, be sure to book in your next round of testing as soon as possible. Contact Voltec Maintenance today.
