An apparatus for regulation of electrical power has 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 in and to provide a mass exchange of the cooling agent between the internal container and an external container. The mass exchange of the cooling agent has 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.
