Plant Services magazine has posted a video showing the effects of an arc flash at three different incident energy levels. Do you know the difference between a 4.6 cal/cm2and a 14.5 cal/cm2 arc flash? Watch the [url='http://www.plantservices.com/multimedia/2011/arc-flash-events-incident-energy-levels.html']video here[/url].

Note that at the time of this post the web page is not correctly designed. In some browsers it is difficult to see the controls for running the video. You can just see the top part of the buttons at the bottom of the video screen. The far left button will start the video. The words will remain on the screen for a long time. The arc flash explosions are shown beginning about 2/3 of the way through the video.
