| Description | 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 surveys? If we believe in the power of convectivecooling, we must realize this will affect our readings on hot spots. Many thermographers simply do not know justhow important wind is in cooling down a hot spot. Also, we do not know how to compensate for convectivecooling effects. This paper gives some interesting data using a simple experiment of blowing air on a hot spot on afuse cutout. |
