Abstract

See full text

In order to enable switching control over power-feeding paths even in the event of a ground fault or an open fault in a power-feeding path, the submarine branching unit is provided with: a switching circuit which switches multiple power-feeding paths formed among a first through a third power-receiving ports; a control circuit which receives power from a power-feeding path formed between the first power-receiving port and the second power-receiving port and controls the switching circuit; and a connection circuit which connects the control circuit between the third power-receiving port and a sea-earth when no power is supplied to the control circuit from the power-feeding path formed between the first power-receiving port and the second power-receiving port.
