  • Patent number: 10199824
    Abstract: In a particular illustrative embodiment of the present invention, an inter-island power transmission system is disclosed. An electronic box is placed on each end of a medium voltage three phase power cable running between two islands. The electronic box senses an open cable on the three phase cable and switches to direct current power transmission on the remaining two good cables. The direct current power is converted back to three phase power transmission on the receiving end of the direct current power.
