Pérdidas Joule en alimentadores que transportan corrientes armónicas en baja tensión

Abstract

A study of Joule losses in electrical feeder lines carrying harmonic currents is presented. Different formulae proposed in the literature were used to estimate the neutral current and electrical losses. In the environment of the Alternative Transients Program, different levels of harmonic distortion were simulated, arriving at findings that show that losses may become considerably higher than in the condition in which active power without distortion is carried. A real case and the importance of reducing the harmonic content associated with losses are analyzed.
