A power supply for simulating lightning-current pulses

The circuit diagram of a power-supply unit for simulating a positive lightning on a system of grounding current pulses is presented. The main criteria that governed the development of this facility are expounded. The design and order of operation of an experimental specimen of a power supply developed at the VNIIEF on the basis of a BMΓ-320 cascade magnetic-cumulation generator are considered. A calculation technique is described with which a device for the formation of current pulses of up to 90 kA in a standard grounding system has been developed.
