Partial discharge
From Academic Kids
(Redirected from Partial Discharge)
In electrical engineering, a partial discharge is a localized dielectric breakdown of a section of dielectrically stressed insulation path that occurs generally in voids, cracks or interfaces within that insulation system or from sharp edges of energized apparatus parts.
The classic form of corona discharge is usually revealed by a glow or brush discharge. Partial discharge in insulation systems may or may not exhibit this.
