The Power Losses in Cable Lines Supplying Nonlinear Loads

This paper presents the skin effect impact on active power losses in sheathless single-core cables/wires supplying nonlinear loads. There are significant conductor when current has a distorted waveform (e.g., diode rectifiers). The authors present new method for loss calculation. obtained results have been compared to IEC-60287-1-1:2006 + A1:2014 standard and based Bessel function. For all methods, were convergent small-cable cross-section areas. proposed gives smaller values these cable sizes than IEC function methods. areas greater 185 mm2, better those other also analyses of extra currents an ideal 50 Hz sine wave is penetration depth factor calculated every considered harmonics, which allows us calculate precise equivalent resistance any size. research part our work thermal analysis that developed.
