DEVICE FOR SIMULTANEOUS REPRODUCTION OF ELECTRIC AND MAGNETIC FIELDS ACCOMPANYING A LIGHTNING DISCHARGE WITH DIFFERENT AMPLITUDE-TIME PARAMETERS Russian patent published in 2022 - IPC G01R31/00 

FIELD: electric and magnetic fields.

SUBSTANCE: invention is intended for simultaneous reproduction of the electric and magnetic fields accompanying a lightning discharge. The substance of the invention lies in the fact that the device for the simultaneous reproduction of the electric and magnetic fields accompanying a lightning discharge with different amplitude-time parameters contains two systems of field formation, a pulsed magnetic field and a pulsed electric field with separate power supply from current and voltage pulse generators, respectively, at In this case, the field formation system that creates a pulsed electric field is made in the form of a strip line consisting of a potential and zero electrode, and the field formation system that creates a pulsed magnetic field is located in this strip line and is made of a single-core high-voltage cable with a semi-conductive sheath made of black-filled polyethylene , and is a flexible structure in the form of two identical parts, having a U-shape, electrically connected in parallel and consisting of straight and loop sections alternating in the following order, adjustable in length: lower straight section - loops - upper straight section, wherein the lower straight sections are electrically connected to the zero electrode of the field formation system that creates a pulsed electric field, and the upper straight sections are electrically connected through active electrical resistance to the potential electrode of the same field formation system.

EFFECT: providing the possibility of simultaneous reproduction of electric and magnetic fields having different temporal and most possible amplitude characteristics accompanying a lightning discharge.
