Partial discharge 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 voids in solid epoxy insulation or bubbles in transformer oil. Protracted partial
Latin word order Latin word order The word order of classical Latin is relatively free. Subject, Object, and Verb can come in any order; adjectives and possessives can go before or after their noun, and so on. A commonly found feature of Latin is hyperbaton, in which a phrase is split up by other words, e.g. "Sextus est Tarquinius" "it is Sextus Tarquinius". A complicating factor in Latin word order is that there are variations between the style of different authors, and also between different genres of writing; in Caesar's historical writing the verb is much more likely to come at the end
