This newsletter is free and will bring you up to date on the issues that surround arc flash and short circuit analysis. Visit us at www.arcadvisor.com for complete product offerings including free online arc flash, short circuit calculators, and PC-based software solutions for short-circuit, arc flash hazard analysis and labeling.
Short circuit calculations using SCA V1.0 software
The example below explains how to build single line diagram of power distribution system using Short-Circuit-Analytic version 1.0 software program, perform short circuit analysis and document the results.
STEP 1: Develop Single Line Diagram and Populate it with the Equipment Data.
Launch SCA V1.0. New project screen will open up.
Develop a comprehensive single-line radial diagram of the power system being analised. It is recommended that you use a copy of the same one-line diagram which is applied when laying out the distribution system. This approach provides the most complete system. Lets use single line diagram represented on Figure 2 below for our example.

Previous edition of NFPA 70E from year 2009 required that labels to display either the available incident energy or the minimum arc flash rating for the Personal Protection Equipment (PPE). Also, every arc flash warning label had to list the system voltage, arc flash boundary, equipment identification and the date of the arc flash analysis listed on it.
