| description | The mathematic model for numerical analysis of external low frequency electric field (EF) disturbance in the dielectric gap between two closely located conducting inclusions, which are placed along the field on a distance less than its sizes, is developed. It is shown that at decreasing of gap between surfaces such inclusions the field intensity inside this gap increases according to the law of power function. Also it is revealed that for fixed sizes conducting inclusions, which located in the line of field, the degree of field intensity in a dielectric gap raises at decreasing of distance between them and with increasing its surfaces curvature. The performed calculations corroborated that at approaching of cylindrical, spherical and ellipsoidal inclusions the degree of field intensity between the last-named is largest, and between the first-named is lowest.

The mathematic model for numerical analysis of external low frequency electric field (EF) disturbance in the dielectric
gap between two closely located conducting inclusions, which are placed along the field on a distance less than its
sizes, is developed. It is shown that at decreasing of gap between surfaces such inclusions the field intensity inside this
gap increases according to the law of power function. Also it is revealed that for fixed sizes conducting inclusions,
which located in the line of field, the degree of field intensity in a dielectric gap raises at decreasing of distance be-
tween them and with increasing its surfaces curvature. The performed calculations corroborated that at approaching of
cylindrical, spherical and ellipsoidal inclusions the degree of field intensity between the last-named is largest, and be-
tween the first-named is lowest. References 8, figures 5.
Key words: electric field, surface charge, dielectric medium, conducting inclusions, intensity, tensed volume.
