Abstract
DETECÇÃO DE FALHA EM CABOS DE ALIMENTAÇÃO SUBMARINOS. A presente invenção refere-se a um método para detectar uma falha em um cabo de alimentação submarino ou em um sistema de aquecimento elétrico direto que compreende um cabo de alimentação submarino. Os pontos de medição são distribuídos ao longo do cabo de alimentação submarino. O método compreende medir em cada ponto de medição uma corrente no cabo de alimentação submarino e comparar as correntes medidas nos diferentes pontos de medição.
