Abstract

The article discusses the problem of determining electrical parameters of superconducting coils with bare windings. Procedures for measuring these parameters are described; in particular, inductance was measured by the voltage of a linear current input at a given rate. Although it is demonstrated to be impossible to determine inductance in a winding with a bare superconductor in the normal state, the inductance of a winding is comparable to that of an insulated wire in a superconducting state at currents below the critical value. The results of measuring the inductance, radial resistance, static current-voltage and magnetic characteristics of two tape coils with bare superconducting windings, one of which had a soldered connection, are presented. The insulated and bare superconducting winding parameters were compared and measurement conditions for the latter were formulated. The results of the study are applicable to the design and operation of superconducting devices with bare windings, such as coils, magnetic storage devices, stator windings of electric machines, etc.
