Partial Discharge Testing Setup for HV Labs by Green-Watt

Partial Discharge (PD) – “Localized dielectric breakdown of a small portion of a solid or fluid electrical insulation system under high voltage stress, which does not bridge the space between two conductors. While a corona discharge is usually revealed by a relatively steady glow or brush discharge in air, partial discharges within a solid insulation system are not visible.”

IEC 60270 – partial discharge measurements – is applicable to the measurement of partial discharge which occurs in electrical apparatus, systems, and components when tested with DC voltage or AC voltage up to 400 Hz.
