This paper presents a study of the self-excitation of thermomechanical self-oscillations of a current-carrying conductor which depend on its electrical resistance, power of joule heat release, and the heat transfer from its surface. The conditions for the occurrence of self-oscillations are determined, and numerical simulation of the excitation of oscillations is performed.
