Abstract:
A method of transmitting an electrical current of at least one phase from a source of electrical current to a load by superconductors with superconducting material cooled to superconducting state, each superconductor having a limiting current carrying value above which a superficial current density corresponding to a magnetic field which reduces the conductivity of the material is produced, and wherein the value of the current to be transmitted is greater than said limiting current carrying value, said method comprising:providing a plurality of magnetically uncoupled said superconductors, the number of superconductors being selected so that value of the current to be transmitted divided by said number is less than said limiting current carrying value; and supplying current of a single phase and of the value to be transmitted to all of the plurality of conductors in parallel whereby the current carried by each superconductor is less than said limiting current carrying value.
