Complete Guide to Arc Flash Hazard Calculation Studies

$79.00

This book by Jim Phillips, P.E. takes Arc Flash to the next level by showing you how to perform the complete Arc Flash Hazard Calculation Study by using a very structured approach to take you through each step from beginning to end.  Using a series of flow charts, examples and calculation worksheets developed by Jim, the study process is broken down into a detailed step by step approach.  You will be taken through many solved problems and examples including arcing short circuit current, incident energy and arc flash boundary calculations. You will also see how to simplify the arc flash study and arc flash labeling as well as understand how to properly model the power system.

This book is the first of its kind to include DC arc flash calculations, worksheets and solved examples explaining the current methods of addressing DC arc flash.

Jim is Secretary of IEEE 1584 – IEEE Guide for Arc Flash Hazard Calculations and is the International Chairman of Geneva, Switzerland based International Electro-Technical  Commission’s (IEC) TC78 Live Working which includes  Arc Flash Protection.  He is also a member of many other codes and standards committees.  Jim was previously the Head of the United States delegation for the IEC Technical Committee 78 – Live Working.   All of this provides him with a very unique perspective from the insider’s view.  His Arc Flash Training Courses have become the industry standard.  Even instructors from other training companies have attended Jim’s classes to see how it’s done.

Book Summary

Step by Step Approach – This book takes the entire Arc Flash Study process and breaks it down into individual steps with one chapter for each step.

Solved Examples – This book is Packed with many solved example problems to help illustrate the details of each equation and calculation method.

Calculation Work Sheets – Solving complex equations such as those used for the study can seem overwhelming. However, Jim takes each arc flash equation and breaks it down into simple steps by using work sheets that he developed to simplify the problem solving process.

Tricks and Traps – Many questions and potential problem areas are frequently encountered when performing the Arc Flash Study. Jim provides many tricks that can be used for the study and also warnings about the potential traps that could be encountered. You will also see how to successfully make assumptions and simplify the overall process.

DC Arc Flash Calculations – Although not part of any standard (yet), this is the first book of it’s kind to include DC arc flash calculations and worksheets with many examples and illustrations based on a few well known technical papers.
