Thomas J. Domin is a registered professional engineer in the state of Pennsylvania, USA. Much of his experience working with electrical power systems was gained during his 40 years at PPL, Inc., a midsized electric utility headquartered in Allentown, Pennsylvania. The scope of his work covers the development of protection standards and practices, specifications for relaying and control logic requirements for protective systems, specifications for protective relay settings, and the analysis of disturbances in electric power systems. In addition to working on electrical systems within the US, he has worked on international projects involving electrical protection and power system operations.

"... provides a solid foundation for the master-level student as well as power engineers new to protection principles, and it is most certainly a valuable reference for the experienced protection engineer. This book provides enough information of historical applications to aid the reader in understanding the protection in service today. The material is presented clearly with examples to provide practice of the fundamentals presented."—Miriam P. Sanders, from IEEE Power & Energy Magazine, September/October 2015"The book describes in a very comprehensive and efficient way main problems of power system protection. The protection principles, criteria as well as relay setting calculation rules are explained in detail, with use of many practical examples. The reader receives a book with all practical knowledge in the field in one band."—Prof. Waldemar Rebizant, Wroclaw University of Technology, Wroclaw, PL"The book addresses interesting and timely topics. By analyzing the review materials I feel that the book is based on a proper fusion of technology and methodology. Besides, I expect that it implements an effective balance between power system protection theory and engineering practice. For this reason I’d like to express a positive opinion about the book project."—Alfredo Vaccaro, Department of Engineering University of Sannio, Benevento, Italy
