Thermographic Scans for Switchboards

Many electrical fires start in the switchboard.

The electrical switchboard is the hub of your electrical system, directing electricity from one or more sources to all your appliances and electrical fittings. It’s
generally comprised of several panels each containing separate circuits controlled and protected by switches.
Switchboards must comply with the current Australian standard including AS/NZS 61439.1: 2016 and AS/NZS 3000:2007 which sets out the minimum requirements including wiring, fault protection and access.

Understand the risks

Any electrical switchboard, regardless of age, is a potential ignition source. As electrical systems begin to have problems, heat is emitted. A noise or hum, or perhaps some warmth coming from the board is a telltale sign that something is wrong, but in the majority of cases the fault is imperceptible without the proper equipment.
Costly claims and property damage can be avoided if these hot spots are located and identified before they turn into a potential fire hazard. The cost of replacing a faulty switch is likely to be very little compared to the damage it could cause.

Conduct a thermographic scan

The most effective way to identify hot spots in an electrical switchboard is to have a thermographic scan conducted by a qualified electrician.  Thermal scanning is a non-invasive diagnostic technique. An infrared camera converts infrared radiation (heat) emitted from the surface of electrical equipment into electrical impulses, without the need to shutdown electrical supply.
These impulses are mapped as colours which represent the various temperatures, identifying equipment flaws and pinpointing any hot spots well before they progress into an electrical equipment failure or electrical fire.
The image that is produced can pinpoint the exact electrical component that is at fault including:
  • Loose bolted connections
  • Worn contacts
  • Inadequate contact pressure
  • Overloads
  • Imbalanced circuits
  • Faulty equipment
  • Damaged circuits
  • Faulty fuses
It will also show if any components are reaching a point where they are likely to fail.
The following temperature differentials are used to  evaluate thermographic scan results
  • 0°C to 10°C Continue to monitor on a  regular basis
  • 10°C to 20°C Repair at next convenient opportunity
  • 20°C to 40°C Repair immediately
  • >40°C Failure imminent; shut down for repair
It’s good practice to conduct a thermographic scan annually as part of a regular, routine maintenance program. The frequency will be dictated by the use of the electrical switchboard.
Thermographic scanning is also beneficial when used to identify heat loss and moisture intrusion in cool rooms and offices.

Checking commercial cool rooms and freezers with thermal imaging

Enterprises that need to store large amounts of goods at temperatures well below the freezing point of water often install large walk in freezers on their premises. These large freezers are capable of keeping whole rooms full of these goods, usually foodstuffs, at very low temperatures. There is just one downside: cooling requires a lot of energy. It is therefore very important that no outside heat leaks in. To make sure that the freezer’s insulation is working properly, thermographers inspect the insulation material with a thermal imaging camera.

In essence inspecting walk in freezers, cold rooms and other types of large commercial refrigeration units is in essence very similar to building insulation inspections. The only difference is the direction of the heat. With building insulation inspections we generally try to detect heat leaking from the inside of the building to the outside air, but with refrigeration units we want to detect heat leaking inwards. But the mechanism of heat leakage is just the same.

If there is any heat leakage this can cause a huge unnecessary expenditure on energy bills.  Detecting these heat leaks in an early stage allows the owner to fix the insulation defects, preventing soaring energy bills. With the energy prices continually rising, the demand for walk in refrigerator and freezer inspections is also growing.

Insulation problems are often found in many of the walk in freezers and cold rooms PSG inspects. Freezers may seem to be very well insulated, but you’d be surprised to see how often newly built refrigeration units have a faulty construction. Sometimes the joints between the insulation panels are not protected properly, creating heat bridges. This can cause a lot of unnecessary energy consumption. In other cases older units might develop insulation faults over time due to wear. In both scenarios the best way to detect these insulation defects is by using thermal imaging cameras.
