Stephen P. Tubbs SKM, ETAP, & EDSA Power System Analysis Tutorials

Es un buen libro, yo lo tengo en PDF pero como me gusto mucho quise comprarlo, aunque más que un libro parece un folleto, la pasta está súper delgada aunque bueno el contenido si se aprecia bien

Best book

Should be updated and more examples shall be added for each software.

I found this book useful, short and sweet.I down loaded the SKM sample program before I purchased the book and learn how to use it before I got this book. I wish I had bought the book first. The book is easy to read and I would have save me some time if I had read it first. It does have different examples that are not furnished with the program. I found them useful to test the program from these other examples.The book starts with a small review of hand methods of calculating these values for Load flow and Short circuits.The next chapters jumps into using the different Programs listed in the title. Everything is covered step by step.Chapter five has some useful information on variation of the results using these programs and a basic cost guide.I was not expecting much from this book so I was surprise how useful it was.As an Electrical Engineering PE, I found this book is very practical.Maybe the Author in his next book would cover Circuit Breaker Coordination using these same programs. I would buy ittoo.I have been using SKM for several buildings now. I wanted to check some of the calcs by hand to double check. To do this I like using The architect method used by Bussman Fuses or using Symmetrical components methods. I ran into a problem finding a sample and simple example of unbalanced line to ground short circuit. Well I revisited this book and there it was on page 21. I did find the formulas in other text books but no examples or if they had an example it was a complicated circuit with two or more swing buses and on and on.The MVA method and per unit method has a lot of examples but they are a little abstract. I like thing simple (old school)for hand calcs.
