Issue #28 - ARCAD website redesigned and revamped

After much hard work, we are pleased to introduce a completely redesigned ARCAD website at Please take a few moments to navigate through the updated website. We hope you enjoy the new design and you'll find time to look through the many pages of information waiting for you behind the new home page. Please feel free to let us know about any suggestions you might have or additional material you would like to see on the website.

We have also recently released new Short Circuit Analytic (SCA) mobile app. The app takes into consideration all of the key electrical parameters of power distribution system including power supply, cables, transformers, motors, generators and performs available short circuit 3-phase and phase to phase fault current calculations in three-phase radial electric power systems. Visit the SCA mobile product page online at for more information.

Did you know that most fabrics recommended for protection against electric arc fires will burn vigorously when exposed to a sufficiently large and sustained exposure fire? NFPA 70E allows flammable clothing with a fabric weight at least 4.5 oz/yd2 to be worn when working on tasks stated low risk. Stating a task as low risk and allowing the use of apparel fabrics may lead to severe injuries and fatalities from clothing ignitions in arc flash incidents. A method predicting the behavior of the fabrics during convective and radiant heating has been developed, and an article describing the method was recently published in the International Association of Electrical Inspectors (IAEI) magazine.
