IR Windows – What, Where & How

Infrared Windows are one of the “hottest” topics in today’s electrical maintenance programs.  IR Window Benefits include cost savings, improved efficiency and increased safety.  In most cases, the cost of purchase and installing IR Windows is quickly recouped in a short period of time.  Below are the basic What, Where & How for IR Windows.

WHAT – An infrared window is designed to permit infrared inspections of electrical components located within switchgear enclosures. Infrared windows consist of a metal or plastic frame that supports an infrared transmissive optic, and  usually have a cover to protect the optic when they are not in use.

WHERE – Installed at strategic locations on switchgear enclosures, IR windows permit infrared inspections to be conducted without having to open or remove panel covers, thereby saving time and money and improving safety.  Proper placement of infrared windows takes into account several factors including location of components within enclosures, internal obstacles such as arc barriers, and required field of view.

HOW – Working with a professional installer or thermographer who is familiar with the subject electrical devices will often yield the best results for window placement.   Qualified electricians who understand proper window placement are often the best choice. When uncertain of correct window placement, electricians may opt to work with an experienced thermographer to help with window siting.
