Thermal imaging is a technique that uses specialised cameras to capture the infrared radiation emitted by objects and surfaces. By analysing these radiation patterns, thermal imaging can detect differences in temperature that may indicate issues such as air leaks, moisture intrusion, electrical problems, or insulation deficiencies.
As you can see in the image below, the board and contacts don't get above 45 degrees (all temps in Celsius), the atmospheric temp is 20 degrees, and the reflected temp is only running at 25 degrees. This sort of readout is typically a sign that all is well. However, if there were a couple of points running at >75 degrees, then that would be cause for closer inspection as it would suggest that the circuits and breakers had excessive heat build up, which could be a result of faulty contacts or worn items that are drawing too much current, therefore creating hot spots that can trigger fires.
So long as temperatures fall under the required temperatures and there is a consistent difference between them (within acceptable tolerances) while ensuring all the scans are taken at a uniform distance, you should be ok. Regular thermographic imaging can help identify irregularities in advance if conducted regularly.
IMAGE WORDING EXPLANATION
Emissivity: the measure of an object's ability to emit IR energy (This is normally a value between 0-1.0 (0 = shiny mirror and 1.0 = black surface). Most surfaces are about 0.9-0.95
Reflective temp: temperature of the background or surrounding area that is reflecting radiation onto the object or surface being inspected
Relative Humidity: Moisture content of the atmosphere (if the lens of the image reader has condensation from high relative humidity, it can interfere with readings.
Atmospheric Temp: Atmospheric temp has an impact on calculating the surface temperature of the item.
Distance: How far away from the item being scanned (you want to ensure consistency in the distance).
Given how easy and cheap it is to check for these issues, it's normally a requirement to have an inspection a couple of times a year to make sure there are no major hot spots developing.
Essentially, thermal imaging is a cheap and effective risk management tool that allows for early identification of warning signs that can result in costly issues like an electrical fire. Cheap, effective, quick and non-intrusive to your business, insurers like them as a cost effective risk management technique.
If you're concerned about the potential risks of electrical fires in your home or business, consider investing in a thermal imaging inspection. By detecting hot spots in electrical equipment or wiring, thermal imaging can help you identify potential fire hazards before they become serious risks. With its ease of implementation, thermal imaging is a valuable tool for safeguarding your business from identifiable exposures not easily seen by the naked eye that can help you avoid costly damages or even save lives.
So don't wait - schedule your thermal imaging inspection today and ensure the safety of your property and everyone who uses it.
