Differential protection is a fast and selective method of protection against short-circuits. It is applied in many variants for electrical machines, trans-formers, 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.

Distance protection provides the basis for network protection in transmission systems and meshed distribution systems. This book covers the fundamentals of distance protection and the special features of numerical technology. The emphasis is placed on the application of numerical distance relays in distribution and transmission systems.This book is aimed at students and engineers who wish to familiarise themselves with the subject of power system protection, as well as the experienced user, entering the area of numerical distance protection. Furthermore it serves as a reference guide for solving application problems.For this fourth edition all contents, especially the descriptions of numerical protection devices and the very useful appendix have been revised and updated.

Der Differentialschutz ist ein schneller, selektiver Schutz, der in vielen Varianten bei elektrischen Maschinen, Transformatoren, Sammelschienen und Leitungen eingesetzt wird. Dieses Buch vermittelt die allgemeinen Grundlagen des Differentialschutzes in analoger und digitaler Technik. Dem Verhalten und der Dimensionierung von Stromwandlern sowie der modernen, digitalen Kommunikation für den Leitungsschutz sind besondere Kapitel gewidmet. Ausführlich werden die verschiedenen Varianten des Differentialschutzes beschrieben und deren praktische Anwendungen anhand konkreter Beispiele erläutert. Ergänzt wird dies mit Empfehlungen für Inbetriebnahme, Tests und Wartung. Das gesamte Design und Management von modernem Differentialschutz wird anhand der aktuellen Siemens SIPROTEC Schutzrelais erklärt. Gleichermaßen Lehrbuch wie Standardwerk, behandelt das Buch alle Themen, die bei Planung, Projektierung und Anwendung des Differentialschutzes zu beachten sind. Es wendet sich an Studenten und Ingenieure, die sich in den Differentialschutz einarbeiten wollen, aber auch an praxiserfahrene Anwender, die den Einstieg in die digitale Technik suchen. Außerdem dient es als Nachschlagewerk zur Lösung spezieller Anwendungsfragen.Diese Auflage bietet alle Inhalte auf neuestem Stand der Schutztechnik.

Der Distanzschutz bildet die Basis des Netzschutzes in Übertragungsnetzen und vermaschten Verteilungsnetzen. Das Buch behandelt die Grundlagen des Distanzschutzes und die Besonderheiten der Digitaltechnik. Einen Schwerpunkt bildet die Anwendung der digitalen Distanzrelais im Verteilungs- und Übertragungsnetz. Für die zweite Auflage wurden alle Inhalte überarbeitet und insbesondere die Produktbeschreibungen auf den neuesten Stand gebracht. Das Buch wendet sich an Ingenieure und Studenten, die sich in das Gebiet des Selektivschutzes einarbeiten wollen, aber auch an praxiserfahrene Anwender, die den Einstieg in die digitale Distanzschutztechnik suchen. Außerdem dient es als Nachschlagewerk zur Lösung von Problemen in der praktischen Anwendung.
