Partial discharge - Wikipedia

In electrical engineering, partial discharge is a localized dielectric breakdown of a small portion of a solid or fluid electrical insulation system under high voltage stress. While a corona discharge is usually revealed by a relatively steady glow or brush discharge in air, partial discharges within solid insulation system are not visible. PD can occur in a gaseous, liquid or solid insulating medium. It often starts within gas voids, such as voids in solid epoxy insulation or bubbles in transfoGet price
