In the case of (RE)BaCuO (T < Tc), the electrical behavior is highly non-linear, and reliable data for (RE)BaCuO in 2G HTS CCs over a wide range of temperature and electric field are not available in the literature. However, the electrical conductivity of (RE)BaCuO ( REBCO) can be reasonably well approximated by using a power-law model in the flux creep and flux flow regimes ( sc), while the transition from the superconducting state to the normal state ( n) can be modeled assuming two resistances in parallel.
