Abstract
PURPOSE: To detect a defective portion continuously in a non-conductive manner during a producing process by measuring the variation in the current flowing through a preset longitudinal section and in the voltage between the desired two points in that section.
CONSTITUTION: The specific resistance of a superconductive element constituting a stabilized superconductive wire and a stabilizing metal are denoted at ρS and ρN; the areas of a section normal to the longitudinal direction of the superconductive wire are denoted at SS and SN; ρS/ρN=A, SN/SS=γ; the electric resistance of the super conductive wire per length l is denoted at R; and the value of the resistance R when the value γ is infinite (which means that only the stabilizing metal is used for SS=0). Then, a relationship of R=[A(1+γ)R0]/(1+γA). If there is any fluctuation in the stabilizing metal ratio γ, the electric resistance for that section is varied. As a result, the defective portion of the metal layer can be detected by measuring the electric resistance of a preset section of the stabilizing superconductive wire by a constant current or voltage method. Thus, even during the production, the detective portion can be detected continuously in a not-destructive manner.
