摘要

The vanishing of the electrical resistance is a key property of superconducting materials when cooled at low temperatures below their critical values. The replacement of normal conducting metals, as copper, by superconductors can result in considerable improvements in the equipments of the power sector with respect to their efficiency, size and performances, allowing a significant energy saving and a subsequent reduction of polluting emissions at the generation sites. The discovery of high temperature superconductors with T_c values above 77 K hold out the promise of superconducting technologies with lower capital and operating cost, if compared to devices based on low T_c superconductors.
