Partial discharge - Wikipedia
In electrical engineering, partial discharge (PD) is a localized dielectric breakdown (DB) (which does not completely bridge the space between the two conductors) of a small portion of a solid or fluid electrical insulation (EI) system under high voltage (HV) stress.
What is Partial Discharge (PD)? Partial Discharge - A flashover of part of the insulation system due to a localized electric field greater than the dielectric withstand capability of that part where the overall insulation system remains capable of withstanding the applied electrical field. Conductor. C1 C2. C3. Void. HF Current Pulse. Ground.
What is Partial Discharge (PD) •An incomplete electrical breakdown between two conductors •Corona is a type of PD, where the PD is occurring on a conductor surface and is the result of a high local (non-uniform) electric stress •Generally PD is only likely to occur on equipment operating at 3.3 kV phase to phase or above
Main causes and types of partial discharge - Fluke Corporation
The standard definition of partial discharge (PD) is an electrical discharge that does not completely bridge the space between two conducting electrodes. Partial discharge occurs in a variety of locations and mediums in high voltage electrical equipment.
The Basics of Partial Discharge Testing - HV Technologies
Partial discharge (PD) is evidence of a degrading insulation system, which could lead to very costly repairs and can predictively lead to an electrical breakdown of high voltage apparatus.
