Abstract:
1. A method for regulation of electrical power comprising the steps of: transporting an electrical current through a superconducting member exhibiting a capability of quenching at the electrical current exceeding a threshold value; transporting an additional electrical current through a metallic member coupled to the superconducting member; filling of a thermally insulated and enclosed internal container with a portion of a liquid fraction of a cooling agent and a portion of a gas fraction of the cooling agent; cooling of the superconducting member and the metallic member by their direct contact with the liquid fraction of the cooling agent in the internal container, and providing a mass exchange of the cooling agent between the internal container and an external container, wherein the exchange of the cooling agent is controlled as a function of both with an interruption of a predetermined duration.
