ABSTRACT:
A branching unit for use in submarine systems that includes a ground termination; first, second, and third cable terminations each coupled to a power feed line of a respective submarine cable; a re-configuration relay in series between the first cable termination and the ground termination, the re-configuration relay being unidirectional and having at least one contact positioned in series between the second and third terminations, the at least one contact being closed when the re-configuration relay is de-energized; and a bypass relay in series between the second and third cable terminations, the bypass relay having a contact positioned in parallel with the reconfiguration relay and being open when the bypass relay is de-energized.
