Protective Relaying: Principles and Applications, Fourth Edition Hardcover – Illustrated, 11 February 2014

First off, this book contains a lot of in-depth material. It is very detailed and contains most information you need for the protection field. However, this is not a book most people can just sit down and read. If you take it piece-by-piece, it is a joy to get through. As others have stated, the binding is not the best, so take extra care of your book. This book does expect you to fully grasp the concepts of power systems. If you have not already had exposure to fault analysis and symmetrical components, I suggest you first read a power system analysis book and then try to tackle this book.If you already have experience in the protective relaying field, this book will serve as a great reference for you. If you are just getting into the field, or want to learn more about protection just for fun, I would suggest this book along with Fundamentals of Power System Protection (Paithankar, Bhide). Read a topic in Paithankar first (like transformer protection), and then read the same topic in Blackburn. Paithankar will give you a condensed and clear explanation of the basics on a topic, and then Blackburn will go into more depth.

Muy buen libro complio lo que requeria

Good source of information

This is my most commonly used reference material on the job. I originally owned a copy of revision three but ended up getting this copy as part of a class I took. It cleans up some of the minor mistakes that the older version had and it brings some more modern references into the book but let's be serious. If you're getting this book, you're mostly getting it for the great detail provided on the principles of protective relaying which have not changed much since their origins. I think I liked the formatting of the older book more, the font, sizing, etc but I find it difficult to remove a star for that when the new one is still perfectly readable. Some of the graphics are still outdated looking and can be difficult to read but if you're already familiar with TCCs and power equipment, you'll be able to fill in the gaps. If you're not familiar, they're an overwhelming abundance of information on the internet to help. Again, I find it difficult to pull a star for that because I'm guessing anyone buying this book is buying it for the principles and not the art. To that point, there are very few printed resources that match up to Blackburn when it comes to principles of protective relaying.

The Bible, a must have for all protection engineers, it helped me a lot in my relay understandings and settings
