A magnetocumulative energy source for reproduction of lightning current pulses on a branched protective grounding system

An energy source based on two magnetocumulative generators with a transformer energy output for reproducing positive-polarity lightning current pulses with amplitudes of up to 200 kA on the protective grounding is described. Results of a full-scale experiment on reproducing a current pulse with an amplitude of about 190 kA on the protective grounding model with a direct-current ohmic resistance value of 4 Ω are presented.
