Abstract

We all know the wind either from environmental sources, fans or blowers will cool things off. Why then, do we often ignore the wind when doing IR thermographic survey? If we believe in the power of convective cooling, we must realize this will affect our readings on hot spots. Many thermographers simply do not know just how important wind is in cooling down a hot spot. Also, we do not know how to compensate for convective cooling effects. This paper gives some interesting data using a simple experiment of blowing air on a hot spot on a fuse cutout.
