Torch discharge active resistance and igniter voltage definition

The method of torch discharge active resistance determination based on experimental results obtained from investigation of torch discharge in single-conductor line is considered in this paper. The method is based on Neiman equivalent scheme described in. In this scheme U_G is discharge ignition voltage, i.e. the voltage when corona discharge transforms to torch discharge. The circuit can be considered like it is shown in fig. 1. Here R_D is active resistance, I_D - operating current for discharge existence and X_C - reactance of capacitor appeared between linear conductor and perfectly conducting plane, which is a screen between the line and the generator.
