The first two discussions covered the extreme heat and blast from an arc flash. These elements of energy are extremely dangerous. What happens after the arc event is the topic of this discussion. If an electrical arc situation predicts the need for a high level of protection, consideration must be […]
This is the second article of four on arc flash. The next arc flash concern after heat energy is blast. The danger comes in the forms of a pressure wave, sound, light, particulates or shrapnel. The pressure wave or blast is the result of rapid heating of the air to […]
In this series of short articles, four aspects of arc-suppression blankets will be covered: (1) heat (2) blast and pressure wave (3) burning and (4) installation suggestions. The major reason for arc-suppression blankets is protection from the intense heat. Although testing has indicated source temperatures of over 30,000 degrees F, […]
