Abstract

La presente invención se relaciona con un método para determinar un estado de un transformador de voltaje capacitivo (50) el cual, en su lado primario, comprende un divisor de voltaje capacitivo que tiene un primer condensador (C1) y un segundo condensador (C2). El primer condensador (C1) tiene una conexión de alto voltaje (HV) para conexión a un alto voltaje (60) y el segundo condensador (C2) tiene una conexión a tierra (NHF). Una primera frecuencia resonante (?e) es determinada por medio de una pluralidad de primeras mediciones de impedancia de corto circuito a diferentes frecuencias en un lado secundario del transformador de voltaje capacitivo (50) mientras que la conexión de alto voltaje (HV) está conectada a tierra (70). Una segunda frecuencia resonante (?2) es determinada por medio de una pluralidad de segundas mediciones de impedancia de corto circuito a diferentes frecuencias en el lado secundario del transformador de voltaje capacitivo (50) mientras la conexión de alto voltaje (HV) está abierta. Una relación de capacitancia (KC) del divisor de voltaje capacitivo (50) es determinada sobre la base de la primera frecuencia resonante (?e) y la segunda frecuencia resonante (?2).
