Understanding what a Partial Discharge is
A partial discharge is an discharge of electricity or a spark between a small piece of the insulation between 2 conducting electrodes. Partial Discharge can happen at any place in the insulating system, where strength of the electric field surpasses the breakdown strength of that section of the insulating material.
