Asymptotical characteristics and similar-
ity of electrostatic fields of solenoids.
Solenoid coils have a number of special
points where occurrence of partial discharge is
the most probable. They are points of sharp
change of curvature equipotencial surfaces on
solenoid edges - special points of I type, or points
of voltage input, in witch growth of potential
changed its direction - special points of II type.
Asymptotical characteristics of electrostatic fields
in these points are different. That is way the defi-
nition of the most probable place of partial dis-
charge is unequivocal. For points with identical
asymptotical characteristics this problem, on the
contrary, has the unique decision due to similarity
of fields in them.
Key words – solenoid, electrostatic field,
partial discharge, special points, asymptotical
characteristics.
