Abstract
The present invention relates to an electrical power transmission system using superconductors which is compatible with conventional transmission systems. In a first aspect, a method for installing in an electrical power transmission system a connection using a coaxial superconducting cable, includes determining a reactance of a conventional cable suitable for the connection; installing the coaxial superconducting cable, and increasing a reactance of the coaxial superconducting cable, in such a way that the reactance of the superconducting cable is substantially equal to the reactance of the conventional cable. In particular, increasing the reactance of the coaxial superconducting cable includes connecting in series with the coaxial superconducting cable an inductive element, preferably made from a superconducting material.
