Overall Current and Voltage Distribution Facilities have been provided at the j unction of the land and sea cables(Terrenceville) to connect a power ground to the center conductor of thecable. Normally this ground will be disconnected, but during installationit enables the land and sea sections to be energized separately and maysubsequently be of assistance in the localization of cable faults nearTerrenceville. The full line in Fig. 2 shows the current path with normal double-endfeeding, while the broken lines show the current paths when a ground isconnected at Terrenceville. The full line (d) in Fig. 3 shows the voltage distribution along the link 2500.
