Lots of lives and properties are lost annually as a result of several kinds of wiring issues.
Some of these issues were visible enough to be fixed but were ignored; others were not visible enough and were only discovered by thermal imaging by forensic analysis.
Either way the losses from electric wiring issues are always monumental.
As a result of the way some wires are hidden they need the aid of a thermal camera handled by a qualified technician or a trained electrician to find irregularities and faults.
What are thermal cameras?
Thermal imaging camera is specially made a thermal imaging device that is used for detecting and observing electrical faults in electrical systems like fuse boxes, transformers, and other systems. They are simple, easy to use, and they have a screen and trigger for capturing images.
How to use thermal cameras
- Ensure that you remove any obstructing material like the cover plate, as these materials affect the measurements.
- Move close to the wires or device and press the trigger to capture the image
- Connect the camera to print out the images for analysis.
Tips to know before you use a thermal camera
- Identify the electrical system and study beforehand: Before you carry out any thermographic analysis, it is vital to identify the system you would be fiddling with and study it. This is important, especially if you are not familiar with it. Doing this will save you time and even save you from surprises.
- Wear appropriate gear for special occasions: Not all electrical systems require a power protective gear (PPG). But if you are going for high energized electrical work, then you should have all your protective gears in place. Ensure that you wear a smart and top-quality gear.
- Go with an equally trained assistant: When it comes to thermographic imaging, two is not a crowd. It is best if the individual goes with an assistant or assistants that will take records, look out for other faults, and act as a second hand and a third eye. An assistant is needed to remove heavy substances like panel boards.
- Avoid working as soon as the fault is detected: Electrical matters should be handled with sensitivity which is why work or repairs shouldn’t begin as soon as flaws or defects are detected on the camera. They can, and they should be taken note of and repairs scheduled until a later date to avoid stress and mistake.
Other things to look out for in electrical systems
- The fuse:A hot fuse will show up on the scan as hot.A blown fuse also has its signature warmness.
- Connections and wiring: The temperature rate in a connection is an indication of the state of the system. Corroded, tight connection always appears warm at the point of the resistance. Shunting always appear cool.
- Transformers: Transformers can be inspected with a thermal camera. If they do not generate adequate heat to be viewed outside, their compartments have to be opened before they can be viewed.
