Abstract :
AC losses and electromagnetic phenomena in assembled conductors composed of YBCO coated conductors arranged in parallel were studied by finite element method (FEM). The analysis tool is based on the current vector potential method with thin-plate approximation and with strongly nonlinear E-J characteristics (E: electric field, J: current density) of superconductor. In this paper the dependence of AC losses and electromagnetic phenomena on the intervals between the conductors was investigated.
