Partial discharge a local area network, via modem or even a via web-based viewer. Partial discharge In electrical engineering, partial discharge (PD) is a localized dielectric breakdown (DB) of a small portion of a solid or fluid electrical insulation (EI) system under high voltage (HV) stress, which does not bridge the space between two conductors. While a corona discharge (CD) is usually revealed by a relatively steady glow or brush discharge (BD) 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
Halo (religious iconography) obsolete "nimbated", like the commoner "nimbate", means "furnished with a nimbus". It is sometimes preferred by art-historians, as sounding more technical than halo. "Aureole", from the Latin for "golden", has been used in English as a term for a gold crown, especially that traditionally considered the reward of martyrs, since the Middle Ages (OED 1220).
