heal.abstract	This work deals with the partial discharges which emanate from solid dielectrics during impulse voltage application. More specifically, a detailed study of the potential steps and the net electronic transfer during luminous partial discharges, has been attempted. The experimental results are in agreement with the argument that allowed energy levels to be present in the energy gap of the dielectrics, possibly due to the irregularities which may be associated with these materials. This encourages electronic transitions towards higher energy levels or bands and contributes significantly to the initiation of impact ionization. As a result, the free-electron multiplication may lead to the occurrence of partial discharges. When the average electronic energy above the metal Fermi level is greater than 7 eV, the electromagnetic energy is expected to vary between UV and thermal radiation.	en
