Method And Apparatus For Regulation Of Electrical Power

An apparatus for regulation of electrical power comprising:

• a superconducting member exhibiting a capability of quenching at the electrical current exceeding a threshold value,
• a metallic member coupled to the superconducting member,
• a thermally insulated and tight internal container filled with a portion of a liquid fraction of a cooling agent and a portion of a gas fraction of the cooling agent,
• the internal container being capable to provide a cooling of the superconducting member and the metallic member by their direct contact with the liquid fraction of the cooling agent, and
• means for providing a mass exchange of the cooling agent between the internal container and an external container, wherein the means for the mass exchange of the cooling agent comprise:
• a mass flow controller for the cooling agent which is output from the inner container;
• a controller of an instantaneous pressure in the internal container, and
• a delay circuit providing a pre-determined time-delay for mass flow controller operation.
