Thermographic Inspections Glasgow

GW Electrics offer Thermographic Inspection Testing in Glasgow and the surrounding areas.

Thermographic Inspection Testing is a heat testing method used to detect poor electrical connections, unbalanced loads, deteriorated insulation, or other potential problems in electrical components and panels such as fuse boards or fuse boxes. Such problems or ‘hotspots’, if left untreated, can lead to excessive and unnecessary power use, increased maintenance costs, or major electrical failure resulting in unscheduled interruptions, equipment damage and other service issues.

Thermographic Inspection Testing - What Is It?

A thermography survey works when infrared radiation is applied to the surface of an object, such as electrical wiring, creating a thermal heat pattern. Testing devices, such as an infrared camera, or a thermographic scan for larger devices, are used to safely detect and convert infrared radiation into either a temperature value or a thermal image, which in turn measures the thermal condition of an object.

Thermographic imaging:

  • instantly detects system and equipment deterioration

  • highlights excessive loading and phase imbalance

  • identifies potential electrical component failure and fire risk from overheating

  • finds faults not always visible by conventional testing

  • tackles problems early to prevent excessive costs in future

  • is unobtrusive testing requiring no shut down or loss of business productivity

As any electrical component deteriorates, its resistance increases, causing an increase in heat. Similarly, a poor electrical connection will have higher resistance than a stronger one and will also result in a higher temperature. Our expert electricians use thermography imaging surveys to detect these temperature differences. Our engineers deliver same day inspection reports, covering all electrical components as part of a dedicated nationwide service.

What Are The Benefits Of Thermography Inspection?

The National Fire Protection Association (NFPA) estimates that 10% of fires occurring in business properties relate to electrical system failures,such as electrical insulation, terminals, and related components. Additionally, failures can cause employees to be exposed to live electrical circuits, making them susceptible to serious injury or death from electrocution. By immediately detecting instances of high-resistance connections and repairing them, breakdown of electrical wires and related components is minimised.

With thermal imaging, potential faults in electrical components are identified instantaneously and the severity of the problem can be understood. The hotter areas will be distinctly brighter on the thermal Image, pointing you directly and instantly to the component causing the problem. We can then provide a suitable solution and undertake remedial action.

We provide a detailed Thermal Imaging Report with every inspection showing the installations details and characteristics, the schedule of items tested and inspected, a thermal image and standard image of the equipment surveyed and recommendations for any further action required with an explanation as to why it is necessary.

How Often Should Thermographic Inspection Testing Be Carried Out?

Most people are generally unsure as to how regularly their electrical appliances should be tested. It really depends on the type of equipment you use and the environment in which you use it. A heavy duty power tool should be examined more frequently, than say, a desktop lamp. Thermographic Inspection Testing and maintenance should be carried out at regular intervals to ensure the continual safety of your colleagues and the security of your business premises.

GW Electrics For Thermographic Inspection Testing Needs

Thermographic imaging equipment can often be complex, and therefore persons performing evaluations and testing require specific training. As there is potential for exposure to “live” electrical components, only a trained and qualified electrician should attend to this.
