Practical approbation of results of calculation of values of R<sub>ce</sub> and T<sub>me</sub> is executed as it applies to air DES, to connected in a discharge circuit of powerful high-voltage CES with protracted C- of component current of artificial lightning, characterized rationed ATP. It is shown that calculation of numeral value R<sub>ce</sub> approximately in 100 times exceeds the proper value of active resistance for the plasma channel of impulsive spark of electric discharge in air DES other things being equal, and a calculation of numeral value T<sub>me</sub> well corresponds with the known thermodynamics information for classic electric arc in air DES of atmospheric pressure with graphite electrodes.<strong> Originality. </strong>New engineering approach is developed for the approximate calculation of values of R<sub>ce</sub> and T<sub>me</sub> in electron-ion plasma of channel of pulse electric arc, arising in air DES of high-current discharge circuit of powerful high-voltage CES of proof-of-concept of electric setting of the technological setting. A formula is first obtained for the approximate calculation of equivalent active resistance of R<sub>ce</sub> of channel of pulse electric arc in air DES, remaining unchanging in the process of high-current discharge on RL- load of indicated CES</em>. <strong><em>Practical value.</em></strong> <em>Drawing on the got calculation results for the values of R<sub>ce</sub> and T<sub>me</sub> in high-voltage impulse technique provides the rational choice of own electric parameters and construction elements of basic devices of powerful high-voltage CES of technological of electric setting, and also account of influence of electrical engineering descriptions of air DES on electromagnetic processes, taking place in the high-current discharge circuit of indicated CES with protracted C- of component current of artificial lightning.</em>}, number={4}, journal={Electrical Engineering & Electromechanics}, author={Baranov, M.
