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
Wastewater discharge standards in Latin America to public sewer system are contained in section V of Decree 883. Congress of Paraguay emitted the Law 1614 of 2000 as the general regulatory and tariff framework for drinking water and sanitary sewer supply. Following the law's guidelines, was created the Quality Regulation for drinkable water supply and sanitation, which applies to the entire national territory. This regulation includes in its Title VI, all what refers to quality of the performance of sanitary sewer supply. In Annex 10 are shown the maximum limits for physicochemical parameters, specifying discharge values for the type of wastewater treatment applied. For purposes of
