Abstract :
In this investigation the behavior of electrode edge corona on insulation surfaces has been explored under several conditions of extreme environment. A majority of tests have been made with a thin electrode adhered to the dielectric, such as an evaporated metal electrode, but some tests have been made with much thicker square edged electrodes resting on the surface. The corona threshold voltage is not very different with unequal evaporated metal electrodes from that previously reported for equal square edge electrodes. The threshold voltage is, as theoretically expected, a function of the ratio of the dielectric thickness to the dielectric constant.
