This book is one of the best to learn power system concepts. Might be a bit difficult for beginners. But it proves to be a great book for advanced learners to gain in depth knowledge about power system operation and control.
Book is written well. Printing is very good. The explanation of every topic is according to post graduation. No topic is written for under graduate students. So, under graduate students it's complete waste of money. Post graduate students (M.Tech.) students go for it.
