What is Electrical Thermal Imaging & How Does It Enhance Workplace Safety?

Electrical systems play a crucial role in modern workplaces, powering essential equipment and ensuring smooth business operations. However, they also come with inherent risks, such as electrical fires, equipment failure, and costly downtime. One of the most effective ways to mitigate these risks and enhance workplace safety is through electrical thermal imaging—a non-invasive, cutting-edge technology that detects potential electrical faults before they escalate into dangerous situations. 

In this blog, we will explore what Electrical Thermal Imaging is, how it works, and why it's essential for workplace safety, particularly in commercial and industrial settings. 

The Importance of Thermal Imaging in Preventative Maintenance 

Thermal imaging is increasingly becoming a critical tool in preventative maintenance programs. At Voltec Maintenance, we've recognised the significant advantages our clients gain by incorporating thermal imaging into their routine inspections. Seeing the potential, we've fully embraced thermal imaging to enhance the safety and reliability of our clients' electrical systems. 

Our Journey into Thermal Imaging 

Our journey began as we initiated thermal imaging with a FLIR E8 camera, originally purchased by Ryan. After conducting numerous inspections with input from experienced technicians, we developed a clear approach to how we wanted to handle our thermal inspections. As demand grew, we completed the Level 1 Thermal Imaging Course in Brisbane with Grant from Gtek, equipping us with deeper knowledge and upgrading our equipment to the more advanced FLIR E54 camera. 

Why Thermal Imaging Matters 

When performed correctly, Thermal Imaging Switchboard testing provides invaluable insights into the operational health of Switchboards and electrical systems. Compared to other preventive maintenance services like Test & Tag or RCD testing, the benefits of thermal imaging are far more impactful. For instance, an RCD might fail a test, but the likelihood of an incident, such as electrocution from a faulty appliance, is relatively low. 

On the other hand, the risks associated with thermographic issues are much higher. Consider an overloaded lighting circuit operating at 90+ degrees Celsius — the potential for a fire is a real and significant threat. Similarly, a loose connection that generates heat over time can lead to severe damage and an increased probability of an electrical fire. From an asset management perspective, thermal imaging not only identifies these risks early but significantly reduces the chance of costly and dangerous incidents. This is why we strongly recommend our clients conduct an annual thermal imaging survey to safeguard their operations. 

How Electrical Thermal Imaging Works? 

Electrical thermal imaging, also known as infrared thermography, is a diagnostic technique that uses infrared cameras to detect heat signatures from electrical equipment. The camera captures thermal radiation emitted by objects and translates it into a visual thermogram, highlighting temperature variations in electrical systems. 

Key Features of Thermal Imaging: 

• Non-invasive: It allows for inspection without disrupting operations. 

• Real-time monitoring: Electrical issues can be identified in real-time without the need for shutdowns. 

• Detailed reporting: The thermal images produced are accompanied by comprehensive reports that highlight any anomalies. 

This technique is particularly useful for identifying two main types of faults: 

1. Overload Faults: When electrical components operate beyond their capacity, they generate excess heat, which can be easily detected through thermal imaging. 
2. Loose Connections: Loose electrical connections cause resistance, which generates heat over time. This excessive heat can lead to damage and eventually cause electrical fires. 

How We Conduct Thermal Imaging Inspections 

Through thermal imaging, we can identify two primary fault types: overloads and loose connections. Overload faults can cause equipment to run hotter than normal, while loose connections generate excessive heat over time, leading to potential damage. By using the FLIR Thermal Studio and advanced reporting tools, we provide clients with detailed PDF reports that clearly outline any issues detected. These comprehensive reports allow for proactive maintenance and repairs, ensuring that our clients' systems remain safe and operational.
