Theories of dielectric failure

This is essentially a continuation of a paper I presented before this group in 1948 and which was printed, with discussions, in the June 1949 Electrical Engineering. Much debate has occurred on the extent to which failure of an insulated single conductor is governed by the maximum stress or the average stress and the relation of failure voltage to the geometry. The behaviors with d-c, a-c, and impulse voltage are all different.
