N2 - The thermal runaway phenomenon in Ag/Bi2Sr2CaCu 2O8 composite conductors was studied for the nonlinear temperature and magnetic field dependencies of their critical current density. The influence of the applied magnetic field, heat transfer coefficient, matrix resistivity and volume fraction of the composite conductor on the static thermal and electric states were investigated. The model is based on steady heat and current balance equations. The model allows to investigate the non-isothermal voltage-current characteristics of composite superconductors.
