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
Planetary health understanding and addressing the human health implications of accelerating change in the structure and function of Earth's natural systems." The Alliance's initiatives include the Rockefeller Foundation Planetary Health Fellowship, a planetary health course for Harvard undergraduates, and a Planetary Health Annual Meeting, which was first held in April 2017 in Boston, MA. The open-access journal "Lancet Planetary Health" published its inaugural issue in April 2017. Planetary health Planetary health refers to "the health of human civilization and the state of the natural systems on which it depends". In 2015, the Rockefeller Foundation and "The Lancet" launched the concept as the
