The improved construction of the coaxial shunt SC-300M intended for measurement of decaying sine and aperiodic pulses of artificial lightning current with amplitudes up to ±220 kA is described. The results of tests of the instrument shunt in the high-current discharging circuit of power high-voltage generator of lightning current (g.l.c.) under pulsed A-component with the first amplitude -198 kA corresponding to time ≈35 µs and an action integral of the simulated pulse of current of lightning discharge equal to ≈2.38 × 106 J/Ω are presented. The quantity of electricity under single action on the shunt by a current pulse of artificial lightning with logarithmic decrement of oscillations ≈2.06 that passed through the current-carrying elements of its construction was ≈-9.9 C. It was shown that, simultaneously with registration of pulsed A-component of lightning current, the shunt, owing to using of a matching voltage divider at the end of its cable communication line, allows also to measure normalized amplitude-time parameters of aperiodic shortened long-term C*-component of artificial lightning current (-568 A; ≈5 ms;τC* ≈18 ms; -16 C) that was being formed in the discharging circuit of the generator.
