# The Use of the Integral Method in the Determination of the Mayr-Voronin and Cassie-Voronin Simplified Mathematical Models of Electric Arc with the Changeable Length of the Plasma Column

Antoni Sawicki

The article discusses the possibility of extending the usability of wellknown integral method formulas used to determine the parameters of the Mayr and Cassie mathematical models of fixed-length arc. Simulation tests discussed in the article involved the simplified variants of the Mayr-Voronin and Cassie-Voronin models of electric arc with dissipated power proportional to the volume of the elongated column. Results obtained in the tests proved the usability of the above-named formulas when calculating the parameters of modified arc models within a wide range of elongation rate changes.
