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.

An all-in-one resource on power system protection fundamentals, practices, and applications Made up of an assembly of electrical components, power system protections are a critical piece of the electric power system. Despite its central importance to the safe operation of the power grid, the information available on the topic is limited in scope and detail. In Power System Protection: Fundamentals and Applications, a team of renowned engineers delivers an authoritative and robust overview of power system protection ideal for new and early-career engineers and technologists. The book offers device- and manufacturer-agnostic fundamentals using an accessible balance of theory and practical application. It offers a wealth of examples and easy-to-grasp illustrations to aid the reader in understanding and retaining the information provided within. In addition to providing a wealth of information on power system protection applications for generation, transmission, and distribution facilities, the book offers readers: A thorough introduction to power system protection, including why it's required and foundational definitions Comprehensive explorations of basic power system protection components, including instrument transformers, terminations, telecommunications, and more Practical discussions of basic types of protection relays and their operation, including overcurrent, differential, and distance relays In-depth examinations of breaker failure protection and automatic reclosing, including typical breaker failure tripping zones, logic paths, pedestal breakers, and more Perfect for system planning engineers, system operators, and power system equipment specifiers, Power System Protection: Fundamentals and Applications will also earn a place in the libraries of design and field engineers and technologists, as well as students and scholars of power-system protection.

Written by two practicing electrical engineers, this second edition of the bestselling Protection of Electricity Distribution Networks offers both practical and theoretical coverage of the technologies, from the classical electromechanical relays to the new numerical types, which protect equipment on networks and in electrical plants. A properly coordinated protection system is vital to ensure that an electricity distribution network can operate within preset requirements for safety for individual items of equipment, staff and public, and the network overall. Suitable and reliable equipment should be installed on all circuits and electrical equipment and to do this, protective relays are used to initiate the isolation of faulted sections of a network in order to maintain supplies elsewhere on the system. This then leads to an improved electricity service with better continuity and quality of supply.

Power system protection systems have three basic components: Instrument transformers, Relays, Circuit breakers The function of the CT is to reproduce in its secondary winding a current I’ that is proportional to the primary current I. The CT converts primary currents in the kiloamp range to secondary currents in the 0–5 ampere range for convenience of measurement. The function of the relay is to discriminate between normal operation and fault conditions. The OC relay in Figure 2 has an operating coil, which is connected to the CT secondary winding, and a set of contacts. When |I’| exceeds a specified ‘‘pickup’’ value, the operating coil causes the normally open contacts to close. When the relay contacts close, the trip coil of the circuit breaker is energized, which then causes the circuit breaker to open. System-protection components have the following design criteria: Reliability: Operate dependably when fault conditions occur, even after remaining idle for months or years. Failure to do so may result in costly damages. Selectivity: Avoid unnecessary, false trips. Speed: Operate rapidly to minimize fault duration and equipment damage. Any intentional time delays should be precise. Economy: Provide maximum protection at minimum cost. Simplicity: Minimize protection equipment and circuitry. Since it is impossible to satisfy all these criteria simultaneously, compromises must be made in system protection. The book consists from the following sections: Chapter 1: Power System Faults: Chapter 2: Instrument Transformers. Chapter 3: Overcurrent and Earth Fault Protection Relays. Chapter 4: Radial System Protection. Chapter 5: Zones of Protection. Chapter 6: Differential Relays. Chapter 7: Distance Relays. Chapter 8: Transformer Protection. Chapter 9: Generator Protection. Chapter 10: Busbar Protection. Chapter 11: Circuit Breakers. Chapter 12: Fuses. Chapter 13: References.
