The features of the change in the average rate of current rise in the load during oscillatory and aperiodic discharge of a reservoir capacitor of electric discharge installations are studied. The regularities of the change in the average rate of discharge currents rise in the load at forced limitation of currents durations and a change in the capacitance of the discharge circuit are determined. It is proved that increasing the capacity of the capacitor reduces the duration of the rise of the discharge current from zero to any fixed value less than the maximum value of the current. Based on this, it is proposed the method for increasing the rate of rise of pulsed currents in the load, which is founded on increasing the capacity of the discharged capacitor and forced interrupting the current in the load when a specified fixed value (or duration) of the current is reached.

Key words: transient, discharge current, capacitor capacitance, rate of current rise.
