The studies of the calculation-experimental determination of the basic peak-temporal descriptions of an electric hasp of long air intervals are resulted in the double-electrode discharge system (DEDS) “edge-plane” by the standard interconnect aperiodic impulse of high voltage of a temporal form of Tm/Тp ≈ 200 μs/1990 μs of the positive polarity. Close calculation correlations were applied for finding the time of Td of the hasp, aggressive (discharge) voltage of Ud, and middle on minimum length of lmin ≥ 1 m of those intervals of an aggressive tension of Ed of a strong electric field for the studied DEDS. The offered engineering approach for the determination of values of Td, Ud and Ed is based on the results of close calculations in the long air interval of DEDS a “edge-plane” is sharp the not-homogeneous strong electromagnetic field and origin under that influence near the potential electrode-edge of this DEDS of the spherical area with the radius of ri of active shock ionization of its atmospheric air electrons, with which the positive leader of discharge develops toward the earthed electrode-plane of DEDS. The executed high-voltage experiments confirmed legitimacy of the offered calculation correlations for the determination of sizes of Td, Ud and Ed at the electric hasp of long air intervals in probed high-voltage DEDS “edge-plane” with their minimum length of lmin from the range of 1 m ≤ lmin ≤ 4 m.
