摘要： [Problem] To suppress current flowing to a contact of a relay when grounding a device to be grounded by connecting the contact of the relay, and to suppress arc discharge between relay contacts when the grounding state of the device to be grounded is released by disconnecting the relay contact.
[Solution] A grounding circuit equipped with: a first relay contact connected to a device to be grounded; a resistor that is connected between the first relay contact and an earth, and that suppresses current flowing to the first relay contact when the contact of the first relay is closed; and a second relay contact that is connected in parallel with the resistor, and that is closed before the first relay contact is opened when the grounding state of the device to be grounded is released.

摘要： Provided is a feedline branching apparatus that makes it possible for additional submarine cables to be installed easily, and with which cost increases can be restricted. For these purposes, the feedline branching apparatus comprises a branching unit and an earth unit. First, second and third terminal stations are connected to the branching unit via first, second and third cables, respectively. When the first and second cables are normal, the branching unit connects a feedline of the first cable to a feedline of the second cable, thereby forming a feedline using a first current. If one of the first and second cables is faulty, the branching unit grounds the feedline of the one of the first and second cables, while connecting the feedline of the other cable to the earth unit. The earth unit grounds a feedline of the third cable, thereby forming a feedline using a second current. When the feedline of the other cable is connected to the earth unit from the branching unit, the earth unit grounds the feedline of the other cable, thereby forming a feedline using the first current.

摘要： A network for transporting communication and power. The network comprises terminal stations branching units and subsea nodes connected to a branching unit, wherein at least one connection path between a terminal station and a first branching unit and between the first branching unit and a first subsea node is provided by means of optical fiber, and wherein said first subsea node is adapted to receive a plurality of wavelengths and provide at least one wavelength at an output thereof. The network comprises a first power supply connected to a first cable head of the trunk cable and at least a second power supply connected to a second cable head of the trunk cable. The first power supply and the at least second power supply, supply at least a minimum amount of electric current in the network either individually or in combination, under normal or faulty conditions.

The PFE is located in at least one of the cable stations. The system also includes an undersea WDM optical transmission cable having a length corresponding to those required in the undersea regional market. The cable includes at least one optical fiber pair for supporting bidirectional communication between the first and second cable stations. At least one repeater is located along the optical transmission cable. The repeater includes at least two optical amplifiers each providing optical gain to one of the optical fibers in the optical fiber pairs. The optical gain is in a range from about 12 to 20 dB.

摘要： In a single wire underwater power distribution system, parallel branching nodes are added in a manner that makes the branch connection and branch line look like a series node to the shore based power source (12). The primary side of a DC-DC converter (53) functioning as an ideal transformer working down to DC is connected into the series line where a branching series line is desired. One side of the secondary creates the branched series path. The other side of the secondary goes to seawater ground, establishing a new local seawater ground.
