Abstract

MÉTODO E DISPOSITIVO PARA DETECTAR FALHA DE UM INTERRUPTOR DE VÁCUO DE UM TROCADOR DE DERIVAÇÃO COM CARGA. A presente invenção refere-se a um método para detectar falha de um interruptor de vácuo em um trocador de derivação com carga, em que o trocador de derivação compreende um alojamento carregado com óleo, um comutador de desvio incluindo um contato móvel (MC, RC), e pelo menos um interruptor de vácuo (MVI, RVI) disposto para interromper a corrente a través do contato móvel do comutador de desvio. O método compreende: repetidamente, - medir um teor de hidrogênio no óleo, e - determinar se há uma falha no interruptor de vácuo (MVI, RVI) baseada na medição do teor de hidrogênio no óleo.
