Heating of contacts closed by short-circuit currents with various waveforms to temperatures exceeding the material recrystallization temperature was calculated. The influence of aperiodic current component on the contact heating behavior was analyzed. Methods for building simplified computational models were proposed to considerably reduce the resource intensity of problems being solved while preserving the acceptable accuracy of results. Keywords: power grid, fault, short circuit, contact, heating.
