Abstract

DIAGNÓSTICO DE BUCHA. A presente invenção refere-se a um método e a um dispositivo (10) para diagnosticar o estado de um aparelho elétrico (14) dotado de um sistema selado de isolamento baseado em fluido. O dispositivo (10) compreende pelo menos uma entrada (24) para o recebimento das medidas de uma corrente que passa pelo aparelho e as medidas de uma pressão de fluido de aparelho real, bem como uma unidade de diagnóstico (26). A unidade de diagnóstico (26) determina uma pressão de fluido de aparelho teórica correspondente com base na medição da corrente, compara a pressão de fluido de aparelho real com a pressão de fluido de aparelho teórica e diagnostica o estado do aparelho com base na comparação.
