Actually, this behavior is reflected in the empirical tables which have
different voltages for the polarities for rod/plane gaps.  For sphere gaps,
the general thing is that the spheres are big enough that the field is close
to uniform, and, anyway, the gap is symmetrical.

There is some stuff in Bazelyan and Raizer on this, too... since it is of
practical use in HVDC transmission..
