Infrared (IR) Windows and View ports essential for professional electrical thermography.

Infrared (IR) windows and view ports are an ideal method for infrared scanning of low voltage (LV), medium voltage (MV) and high voltage (HV) whilst online in accordance with safety standards such as NFPA70E.

Electric Arc-Flash is a dangerous problem associated with live electrical equipment, since infrared thermography should only be performed on systems operating at =<40% rated load (NFPA70B) the installation of infrared windows allows thermographers to remain safe whilst completing a comprehensive infrared scan.

www.irwindows.com provides information on the latest infrared window, sightglass and viewport technology available. The root cause of an arc-fault and corresponding arc-flash event can be condensed to the following;

• Equipment Failure,
• Dynamic Intervention,

A common misconception in the infrared thermography industry is that arc-fault events are the only means by which electrical equipment can fail. Additionally, there are two types of "fault"; Bolted Fault - a low impedance short between two un-synchronised supplies, Arc-Fault - high impedance short causing a plasma arc with unlimited current carrying capability.

Any infrared window should be able prevent dyamic intervention and protect against arc-flash resulting form equipment failure. Such "Arc-Resistant" infrared windows are very important and provide the best option for infrared thermographers.
