Book Description

For many years, Protective Relaying: Principles and Applications has been the go-to text for gaining proficiency in the technological fundamentals of power system protection. Continuing in the bestselling tradition of the previous editions by the late J. Lewis Blackburn, the Fourth Edition retains the core concepts at the heart of power system analysis. Featuring refinements and additions to accommodate recent technological progress, the text:

  • Explores developments in the creation of smarter, more flexible protective systems based on advances in the computational power of digital devices and the capabilities of communication systems that can be applied within the power grid
  • Examines the regulations related to power system protection and how they impact the way protective relaying systems are designed, applied, set, and monitored
  • Considers the evaluation of protective systems during system disturbances and describes the tools available for analysis
  • Addresses the benefits and problems associated with applying microprocessor-based devices in protection schemes
  • Contains an expanded discussion of intertie protection requirements at dispersed generation facilities

Providing information on a mixture of old and new equipment, Protective Relaying: Principles and Applications, Fourth Edition reflects the present state of power systems currently in operation, making it a handy reference for practicing protection engineers. And yet its challenging end-of-chapter problems, coverage of the basic mathematical requirements for fault analysis, and real-world examples ensure engineering students receive a practical, effective education on protective systems. Plus, with the inclusion of a solutions manual and figure slides with qualifying course adoption, the Fourth Edition is ready-made for classroom implementation.

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."
