Abstract
A method for the indirect measurement of load impedance during a progr ammed discharge of capacitive energy storage is reported. According to this method, the load inductance is estimated using a stepwise variat ion of the output storage voltage. The load resistance is determined a t the maxima of the load current. The inductance and resistance of a c hannel of pulsed are discharge in air at atmospheric pressure are esti mated. Measured changes in the inductance comply with evolution of the arc discharge channel observed using highspeed film photography.
