This paper deals with the electrical and thermal characteristics analysis of stacked coated conductors (CCs) for current lead application. A test sample is fabricated using YBCO CCs with a stainless steel laminated stabilizer and has a heater made of the Ni-Cr wire to generate external heat disturbance. In order to evaluate a thermal stability behavior, minimum quench energy, voltage, and temperature trace are measured as a function of operating current. To verify thermal behavior in stacked CCs, numerical analysis on temperature trace is carried out using the finite-element method. The numerical simulation results are compared with the experimental data to check the validity of the simulation model.
