Thermal Imaging

Non-Contact Infra Red Thermal imaging maintenance is a safe and reliable method and is used for inspections of electrical systems and components in all sizes and shapes by our trained electrical personnel.

There are a multitude of applications for non-contact thermal imaging maintenance within the range of electrical systems including Low voltage as well as High voltage installations.

Switchboard thermal surveys are required when carrying out routine inspection and testing of electrical installations under AS/NZS 3000:2007 Wiring Rules.

More and more business owners are required to provide thermal switchboard survey reports to insurance companies as part of their commercial premises fire risk assessment. Switchboard thermal survey reports have become a valuable business document that can lower insurance premiums and help businesses save money.

Switchboard Inspections & The Wiring Rules The testing, measurement, and result recording procedures for switchboard thermal surveys are described in the testing and inspection provisions of AS/NZS 3000:2007 Wiring Rules through their alignment with AS/NZS 3019:2007 Electrical installations-Periodic verification.

Under Section 5 “Verification by visual inspection and full testing of an electrical installation”, clause 5.8 “Integrity of switchboard connections” states:

“With normal operating loads being supplied for at least 30 minutes, the temperature of switchboard components shall be measured and compared to the ambient temperature to ensure that there is no excessive rise in temperature.

Switchboard thermal surveys are a routine visual inspection under AS/NZS 3019 and are carried out by a licensed electrician and can save costs for the business.

 

Professional Tools & Report Outputs

Following the completion of the site inspection, a report will be developed outlining the results.

Analysing thermal images and creating a comprehensive inspection report including results & recommendation is a key output to the process.

Powerful temperature analysis tools: multiple spots, areas, temperature difference measurement.

Armed with good analysis information from the report provided, you’ll be able to clearly identify where potential problems are located. This will also allow you to mitigate risks with predictive preventative & planned maintenance where required.

 

For Low Voltage Installations Thermal imaging maintenance services are used for inspections of electrical systems and components in all sizes and shapes an

their use is by no means limited to large high voltage applications alone.

Electrical cabinets and motor control centres are regularly scanned with a thermal imaging maintenance services. If left unchecked, heat can rise to a point that

connections melt and break down; as a result, fires may break out. In addition loose connections in electrical systems suffer from load imbalances,

corrosion, and increases in impedance to current.

Thermal imaging inspection services using our trained electrical resources can quickly identify hot spots, determine the severity of the problem, and help establish the time frame in which the equipment should be repaired.

Examples of failures in low voltage equipment that can be detected with thermal imaging:

 • High resistance connections

• Corroded connections

• Internal fuse damage

• Internal circuit breaker faults

• Poor connections and internal damage

 These and other issues can be spotted at an early stage with a thermal imaging maintenance. Our approach and trained personnel will help you and your business

prevent costly damages as well avoid dangerous situations.

This option can be employed to assist analyses and can also be used to determine balancing of electrical installation and can assist with maximum demand consideration where other information is collected including time of day and verification of tenancy & services operating.

For more comprehensive maximum demand determination it’s recommended that Power Condition Monitoring Analyses Services, including calculations are provided as a separate option

 

For High voltage installations heat is an important factor in high voltage installations. As electrical current passes through a resistive element, it generates heat.

An increased resistance results in an increase in heat.

Over time the resistance of electrical connections will increase, due to loosening and corrosion for instance. The corresponding rise in

temperature can cause components to fail, resulting in unplanned outages and even injuries. In addition, the energy spent on generating

heat causes unnecessary energy losses. If left unchecked, the heat can even rise to the point where connections melt and break down;

as a result, fires may break out.

Some examples of failures in high-voltage installations that can be detected with thermal imaging:

 • Oxidation of high voltage switches

• Overheated connections

• Incorrectly secured connections

• Insulator defects

These and other issues can be spotted at an early stage with a thermal imaging camera. A thermal imaging camera will help you to accurately

locate the problem, determine the severity of the problem, and establish the time frame in which the equipment should be repaired.

Our services can provide certainty that your facility maintains productivity up-time and efficiency  up, as well as saving you money with predictive & preventative maintenance.
