Experimental Determination of the Electric Field Gain Coefficient on the Top of the Spherical Electrode on Air

Afanasyeva M.

The paper presents the results of air
penetration strength experimental studies for a
two-electrode system consisting of a small radius and
plane hemispheres as the method of technical equipment
testing for determining their resistance to electrostatic
discharges. The hemisphere radius is much smaller than
the distance between the electrodes, so the mathematical
expression is used since the 50s of the last for the formal
determination of the electric field intensification (gain)
coefficient value on the hemisphere radius normally
directed to the plane. Because of comparing the
experimental data obtained by the magnitude of the
electric field gain with the calculated values using the
above formulas, it was concluded that these expressions
are applicable for solving more complex physical and
technical problems related
