The use of infrared (IR) inspection windows in industrial applications has grown exponentially over the past five years. Much of the recent acceptance has coincided with the increase in the level of awareness regarding electrical safety and risk reduction. Organizations such as OSHA, NFPA, CSA, IEEE, ANSI and NETA have been at the vanguard of this movement.
The use of IR windows to facilitate safer, more efficient inspection of energized electrical equipment has outpaced the infrared industry in general. Today, switchgear manufacturers regularly install IR windows at the point-of-manufacture. This, in turn, has generated additional impetus for firms to retrofit existing equipment.
