There are many types of windows available in the market such as IR window, UV window, and Optical Window. This article will guide you about the IR windows, and how they work. So, let us first see what IR windows are.
What Is An IR Window?
An IR Window or infrared window is an optic that is designed for permitting infrared inspections of electrical components located within switchgear enclosures. These windows either have a metallic or plastic frame to support an infrared transmissive optic.
Along with that, these windows generally come with a protective cover for the optic when they are not in use. Based on the type of window, the optics are either made from crystal or polymer material.
How Does An IR Window Work?
An infrared window can be seen as a data collection point which is installed in the metal cover of the electrical switchgear. The different parts of the window include a back ring, the lens, and a front ring with a cover for protecting the opening.
This setup helps in creating a secure housing for the lens and also forms a barrier between the interior and exterior environments. When you are choosing an IR window for installing in your system, you must keep in mind the following factors:
- The available field of view
- The camera lens compatibility with the window
- Intended environment components
- Safety considerations
Who Should Install The Infrared Windows?
As we read that the IR windows installations require modification in electrical enclosures, you must contact trained and qualified electricians to do the installation job. They have a better understanding about the proper window placement, which is extremely important.
If an electrician is not sure about the correct window placement, he generally chooses to work with an experienced thermographer to help with window sighting.
You must ensure that all the targets are identified properly. Along with the fuses and breakers, you must include all the cable and bus connections, and other mechanically fastened connection. Don’t forget to put IR ID labels during the installation to ensure repeatable data collection during IR inspections.
