Electrical Current Transmission by dc Magnetic Coupling in High Tc Superconductors

点击翻译按钮获取中文摘要

This project deals with high temperature, Tc (77K) superconducting material. It deals with a novel method of current transmission by D.C. magnetic coupling in these materials by using a chain of superconducting D.C. transformers linked by a D.C. magnetic field. The practical limitations of the proposed linkage scheme will be explored by initially using an ordinary insulated superconductor, such as lead wire, and test its power transmission efficiency at liquid helium under simulated load conditions. This will be followed by conducting similar experiments using the high Tc superconducting oxide ceramic material at liquid nitrogen.
