In the paper are derived analytical expressions for calculation of values of transient resistances of electric arc in the case of interphase short circuits and also is performed numerical MATLAB simulation of electric arc in transient process. Modelling and simulation of electric network and arc was conducted in MATLAB Simulink surrounding, within the mathematical program MATLAB for simulation of transient processes. Empirical approach based on experiment was used in forming of analytical model of arc. Analysis was performed for two-phase and three-phase short circuits in the network, and real parameters of arc impedance are presented in Tables. Model has practical application because all parameters used in analysis can be obtained by measurement.
