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,
Wastewater discharge standards in Latin America that produces a contamination on the water. In the case of the discharge over sewer systems the regulation is under the Chapter IV.
