PROCÉDÉ DE PARAMÈTRES DE TRAVERSÉE RELATIFS POUR ÉVITER L'INFLUENCE DE LA TEMPÉRATURE DANS LA SURVEILLANCE DE PARAMÈTRE DE TRAVERSÉE ABSOLUS D'UN TRANSFORMATEUR

摘要

The present invention relates to a method and monitoring device, for monitoring N number of transformer bushings operating in substantially the same environment. N being any number more than 1. The method comprises estimating (S2) an absolute value for the capacitances of each of the bushings, the absolute values for the capacitances being denoted C
