Arc flash applications are increasing in popularity among engineers and electricians when examining hazards presented by an arc flash. Professionals search for accessible tools to help reduce dangers associated with arc flash as well as to assist in selecting adequate personal protective equipment (PPE). Mobile apps for arc flash analysis can be useful for assessing the hazards before working on energized equipment.

Contrary to many simple and complex computer programs used for power system and arc flash hazard analysis, only a handful of arc flash apps are available for purchase. Each app, available in either the Apple Store (iPhone) or...

Advanced approaches to addressing direct-current arcing faults

BY MICHAEL FURTAK & LEW SILECKY, Mersen

Let’s face it: there is not very much information available about direct current (DC) arc flashes. And, if you have searched in vain, well hopefully this feature will give you some insight into arc flash with relevance to DC circuits. Essentially, we want customers to be armed with information so that they can accurately determine the necessary level of protection required when working around these circuits.

In this feature, direct-current arcing fault incident energy calculations are presented to assess the level of risk involved when working...
