Zusammenfassung
Das Kap. 12 hat die Laborbewertung von gealterten, gebrauchten oder ausgefallenen Leitungs-Verbundisolatoren zum Inhalt. Der Begriff Laborbewertung wird gewählt, weil der Zustand der Isolatoren nicht als On-Line-Diagnose, sondern als Off-Line-Diagnose erfolgt. Für die Bewertung des technischen Zustandes werden verschiedene Konzepte, Methoden und Hilfsmittel beschrieben, die eine Abschätzung der verbleibenden Einsatzdauer von Verbundisolatoren repräsentativ für die untersuchten Typen und/oder Jahrgänge ermöglichen. Die zu bewertenden Verbundisolatoren werden gezielt der Leitung entnommen, um dezidierte Ergebnisse für diese Isolatorengeneration zu erhalten. Es ist festzuhalten, dass die Normung von Verbundisolatoren auch unter interaktiver Berücksichtigung von Freilufterfahrungen einen hohen Reifegrad erreicht hat. Dies ermöglicht es heute, dass aus den Normen, die für die jeweilige Bauartvielfalt sinnvoll anwendbaren Prüfungen zur Diagnose entnommen werden können. Im Vergleich zur 1. Ausgabe wurden der Wissensstand aktualisiert und weitere Beispiele ergänzt. Wann immer möglich, wurde auf die aktuelle Normenlage in IEC und auf Publikationen der CIGRE referenziert.
