Abstract:
The use of Superconducting power transmission cable is expected to take a step towards the solution for the losses in transmission of power in metropolitan areas. High temperature semiconductor tapes, with liquid Nitrogen cooling system, enables cable operation which is to mitigate the consequences of fault in the system. This will lead to the following merits: (1) carrying large transmission capacity in compact dimension, (2) small transmission loss, (3) no leakage of electro-magnetic field to the outside of the cable, and (4) small impedance. These features are effective for the improvement of reliability and economic competitiveness of electrical networks. With project demonstrations going on around the world in other to accelerate the application of a better network system, superconducting cable is necessary. High temperature superconductivity (HTS) has the potential for achieving a more fundamental change to electric power technologies than has occurred since the use of electricity. It is with the features listed above that ceramic superconducting alternative with higher capacity while eliminating resistive losses, supplant copper electrical conductors.
