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.
