Abstract

PROCESSO E DISPOSITIVO PARA DETERMINAR A UMIDADE RELATIVA DE UM APARELHO ELÉTRICO CARREGADO COM LÍQUIDO ISOLANTE. A presente invenção refere-se a um processo para determinar a umidade relativa de um aparelho elétrico carregado com líquido isolante (20) compreendendo um recipiente (1) contendo liquído isalante (2) e gás (3), uma unidade de comunicação (4) provendo a comunicação entre o gás (3) do recipiente e o gás de um ambiente externo e provendo a desidratação do gás que passa através da unidade de comunicação (4), em que o processo compreende: medir e armazenar continuamente a umidade relativa do gás (3) no recipiente (1), calcular um valor médio da umidade relativa no gás (3) com base nas ditas medições da umidade armazenadas durante um certo período de tempo, e determinar a umidade relativa do líquido isolante (2) com base no dito valor médio da umidade relativa no gás (3) e uma relação entre a umidade relativa do gás (3) e a umidade relativa do líquido isolante (2) em equilíbrio.
