Abstract

Die Erfindung betrifft ein Verfahren zur Funktionsüberwachung von Stufenschaltern, wobei eine für die Funktion relevante Meßgröße erfaßt, der jeweiligen Position des Stufenschalters während der Umschaltung zugeordnet und in anschließende Teilbereiche, die bei einer Umschaltung nacheinander ablaufenden Teilfunktionen entsprechen, unterteilt wird. Innerhalb jedes Teilbereiches wird nach einer bestimmten Rechenvorschrift ein einziger charakteristischer Wert gebildet, dieser mit einer Parameterdatei verglichen und ihm im Ergebnis eine Kennung zugeordnet. Nur diese Kennung wird weiterverarbeitet, gespeichert und dient zur Erzeugung kennungsabhängiger Meldungen bzw. Informationen.The invention relates to a method for function monitoring of tap changers, one of which relevant measured variable for the function, the respective position of the tap changer during assigned to the switchover and into subsequent sub-areas that occur during a switchover correspond to successive sub-functions. Within each Subarea becomes a single characteristic value according to a certain calculation rule formed, this is compared with a parameter file and the result is an identifier assigned. Only this identifier is processed, saved and used for generation ID-dependent messages or information.
