Losses in electrical systems Losses in electrical systems In an electrical or electronic circuit or power system, losses can be classified into two categories: technical and non-technical losses. The term technical losses refers to part of the energy in play dissipates by unwanted effects, including energy lost by unwanted heating of resistive components (electricity is also used for the intention of heating, which is not a loss), the effect of parasitic elements (resistance, capacitance, and inductance), skin effect, losses in the windings and cores of transformers due to resistive heating and magnetic losses caused by eddy currents, hysteresis, unwanted radiation, dielectric loss, corona discharge,
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
