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,[1] unwanted radiation, dielectric loss, corona discharge, and other effects. These losses are typically well under 10%. They are also discussed here electric power transmission

The complementary non-technical losses (NTL) appear during the distribution of electricity. NTL include, but are not limited to, meter tampering, bypassing meters, arranged false meter readings, faulty or broken meters, un-metered supply, and technical and human errors in meter readings, data processing and billing. NTL are reported to range up to 40% of the total electricity distributed in certain countries[2].
