About the Book

Die Sicherung einer ungestorten Stromversorgung ist del' oberste Leitgedanke bei der Ausgestaltung del' elektrischen Erzeugungs- und Verteilungsanlagen. Den MeBwandlern kommt in diesem Sinne eine besondere Bedeutung zu. Ihnen obliegt es, die Vorgange im Netz den an ihre Niederspannungswicklungen angeschlossenen Geraten fUr Netz- schutz, Messung und Zahlung sowohl im Normalbetrieb als auch im Storungsfall richtig zu vermitteln. Ein Versagen del' Wandler ist gleich- bedeutend mit dem Ausfall der Messung, Zahlung und vor allem des Schutzes. Es gelingt dann nicht, eine Fehierstelle moglichst schnell und eng begrenzt aus dem gesunden Netz herauszu16sen, so daB sich eine umfangreiche Storung ausbildet. Fur den sicheren Netzbetrieb ist es daher notwendig, die Wandler richtig zu bemessen und auszuwahlen. Dies setzt die genaue Kenntnis der Gefahrenquellen, ihrer Wirkung auf die MeBwandler und die Moglich- keiten, die die Wandler bieten, voraus. Das vorliegende Buch wurde seine Aufgabe nur unvollstandig erfullen, wenn es sich mit den MeB- wandlerproblemen allein beschaftigen wurde. Den Gefahren und ihrer Beherrschung durch geeignete Auswahl, Bemessung und Konstruktion ist daher ein verhaltnismaBig breiter Raum gewidmet. Es bedarf kaum des Hinweises, daB die vornehmste Eigenschaft der MeBwandler, die MeBgenauigkeit und die Moglichkeiten, diese zu verbessern, unter den verschiedensten Bedingungen gebuhrend er- wahnt werden. Dem Stromwandler fallt bekanntlich zusatzlich die Aufgabe zu, die sekundar angeschlossenen, gegen Dberstrome empfindlichen Gerate zu schutzen. In dem entsprechenden Abschnitt werden den bisher recht unklaren Anschauungen auf Grund neuer Erkenntnisse praktisch brauch- bare Berechnungsverfahren gegenubergestellt, die sicher eine wesent- liche Bereicherung gegenuber dem bisherigen Stand der Technik dar- steIlen.
