The time dependences of the resistance of plasma-erosive load are investigated. For the first time, two new characteristic area of the first mode of this dependence were revealed. As a result of their analysis, the phenomenon of re-appearance of streamer and leader plasma channels after the disappearance of most of the previously formed plasma channels has been substantiated. Taking intoaccount two new characteristic area of the first mode, the dependence of the resistance of the plasma-erosive load on time, its refined parametric model was created. The values of the parameters of this model that are optimal by the criteria of the three main parameters of the residual of the approximation are found. Functions that approximate the dependence of these parameters on theamplitude of the voltage pulses applied to the load are proposed and the optimal values of their coefficients are found. In the Mathlab Simulink software package a model of a discharge-pulse system with a refined parametric model of plasma-erosive load was created and transients in it were calculated. An assessment is made of the adequacy of transient simulation compared with real  processes. References 18, figures 4, tables 4.
