Abstract
trata-se de um sistema de isolamento de falha de aterramento (100) e circuito de isolamento de falha de aterramento para isolar falhas de aterramento em linhas condutoras submarinas elétricas. o sistema inclui um núcleo de potência principal, uma pluralidade de controladores digitais conectados de modo operativo ao núcleo de potência principal através de linhas condutoras submarinas elétricas e um circuito de isolamento de falha de aterramento (100). o circuito de isolamento de falha de aterramento inclui uma pluralidade de cargas conectadas a um circuito de detecção de falha de aterramento (12), sendo que cada carga inclui um relé (22) no barramento de potência positiva (18) e um relé (26) no barramento de potência negativa (20). o circuito de detecção de falha de aterramento é conectado a um circuito de isolamento de cc para cc (10) que impede uma falha de aterramento de barramento de potência principal no caso de uma falha de aterramento em uma das cargas. os relés são conectados a um controlador digital (16) na outra extremidade, que isola uma carga quando uma falha de aterramento é detectada, mas alimenta as cargas não afetadas restantes.
