Use A Thermal Camera To Maintain And Diagnose Electrical Problems

Posted on: 16 August 2016

If you are an electrician, you know that trying to track down a glitch in the electrical system can be difficult. There are a lot of little places that the glitch could be, and no one wants to have to tear apart a whole wall in order to track down one small problem. There are new tools that you can use that will make it easier to track down the glitch in the system and make it work again. One of those is a thermal imaging camera. 

Thermal Camera

Thermal cameras are also known as FLIR cameras or infrared cameras. That's because they don't use the available light spectrum to show an image. What they use is infrared, which is below the light spectrum that you can see with your naked eye. It is expressed as heat. The camera is designed to pick up that energy and transfer it to a screen. When you look at the screen, the hottest spots will show up as the brightest spots on the screen and the spots that aren't putting out any heat will be dark spots. 

Thermal Cameras and Electrical Systems

There are several ways that you can use a thermal camera when you are working on electrical systems. One is that you can use it to help with preventative maintenance to help avoid problems or fix them before they get too bad. Another is that you can use it as a diagnostic tool to try to figure out what the problem is and to fix it. 

Preventative Maintenance

One way that you can use a thermal camera to help do preventative maintenance on your electrical system is to check for corroded or loose connections in any outlets or electrical panels. You will want to do this with the power on so that all the circuits are active and generating heat. Loose or corroded connections are going to generate more heat than a connection that is in good shape. That means that they will show up brighter on the camera's screen. 


Using the thermal camera to diagnose a problem will be similar to using it to help to maintain the electrical system. The biggest difference is going to be that you know that there is a glitch in the system, but you are just trying to figure it out. If you have been able to rule out easy things and think that the problem is inside the wall, the camera can let you see if the problem is with a frayed wire inside of the wall. 

Figuring out a way to do your job easier can mean that you don't have to tear apart a wall to find a solution. For more information, contact local professionals like Weller Infrared Services.


Talking About Rewiring Your Building

Hello, I am Ryan. When I was looking to upgrade my home, I knew that the wiring in my home needed to be replaced first off. The wiring was unable to handle the demands of my modern entertainment equipment. I contacted an electrician to discuss the wiring replacement process. The job was very involved, but well worth the time and effort. I will use this site to explore the tools and techniques used by electricians when replacing wiring in homes. I would like you to visit my site often to learn about this important task. Thank you for visiting my site.
