Improve Failure Detection and Optimize Protection In the ever-evolving field of protective relay technology, an engineer’s personal preference and professional judgment are as important to power system protection as the physical relays used to detect and isolate abnormal conditions. Invaluable Insights from an Experienced Expert Protective Relay Principles focuses on probable power system failure modes and the important characteristics of the protective relays used to detect these postulated failures. The book presents useful new concepts in a way that is easier to understand because they are equally relevant to older, electromechanical and solid-state relays, and newer, more versatile microprocessor-based relays. It introduces the applications, considerations, and setting philosophies used in transmission-line, distribution-line, and substation applications, covering concepts associated with general system operations and fault detection. Topics include relay load limits, cold load pickup, voltage recovery, and arc flash. The author also delves into the philosophies that engineers employ in both urban and rural areas, with a detailed consideration of setpoint function. Analysis of Key Concepts That Are Usually Just Glossed Over This versatile text is ideal for new engineers to use as a tutorial before they open the instruction manuals that accompany multi-function microprocessor-based relays. Guiding readers through the transient loading conditions that can result in relay misoperation, the author elaborates on concepts that are not generally discussed, but can be very helpful in specific applications. Readers will come away with an excellent grasp of important design considerations for working with overcurrent, over- and undervoltage, impedance, distance, and differential type relay functions, either individually or in combination. Also useful for students as a textbook, this book includes practical examples for many applications, and offers guidance for more unusual ones.

Differential protection is a fast and selective method of protection against short-circuits. It is applied in many variants for electrical machines, transformers, busbars, and electric lines. Initially this book covers the theory and fundamentals of analog and numerical differential protection. Current transformers are treated in detail including transient behaviour, impact on protection performance, and practical dimensioning. An extended chapter is dedicated to signal transmission for line protection, in particular, modern digital communication and GPS timing. The emphasis is then placed on the different variants of differential protection and their practical application illustrated by concrete examples. This is completed by recommendations for commissioning, testing and maintenance. Finally the design and management of modern differential protection is explained by means of the latest Siemens SIPROTEC relay series. As a textbook and standard work in one, this book covers all topics, which have to be paid attention to for planning, designing, configuring and applying differential protection systems. The book is aimed at students and engineers who wish to familiarise themselves with the subject of differential protection, as well as the experienced user entering the area of numerical differential protection. Furthermore, it serves as a reference guide for solving application problems. For the new edition all contents have been revised, extended and updated to the latest state-of-the-art of protective relaying.

The Relay Protection of High Voltage Networks presents the theoretical aspects of relay protection of high-voltage electrical networks. This book covers a variety of topics, including sequence networks for complex asymmetrical states, vector locus method, theories of symmetrical component filters, and power directional devices. Organized into 10 chapters, this book begins with an overview of the use of sequence networks. This text then examines the relay protection of high-voltage networks with three-phase and single-phase tripping. Other chapters consider the principles of auxiliary devices, which serve for the selection of the faulty phase and for preventing the incorrect operation of protective gear during swings and for faulty conditions in the secondary windings of voltage transformers. The final chapter deals with the stability of parallel working of power stations in a system. This book is a valuable resource for engineers, student, research workers, and readers specializing in the field of relay protection.
