Shielding property of Bi-2223/Ag multifilamentary tapes is analyzed based on the finite-element method. Quantitative expression of electric field versus current density, which is expressed as a function of temperature, magnetic field intensity and its applied direction, is taken into account. Detailed cross-sectional structure of the Bi-2223/Ag multifilamentary tape is also modeled for the precise analysis. It is shown that the power-law approximation of J-E curves (so-called n-value model) is inadequate to the analysis of the fault current condition. It is also to be reported that the shielding property of the multifilamentary tape is different from that of the monofilamentary tape. These results are crucial to the limit design of the HTS cable.
