Resistance Approximation In High Harmonic Frequencies

Sayenko Y. L., Kukhun W.

Electrical Power Quality and Utilisation. Journal

2009

Vol. 15, iss. 2

43--46

The problem of consideration of the resistance in calculation of non-sinusoidal regimes in electrical networks is considered in article. It is shown the necessity of taking in account the skin effect in harmonic frequencies. Using general electromagnetic field theory in condition medium and Bessel’s function allow to obtain expressions of resistance approximations in high harmonics frequencies for conductors of round cross-sectional areas.
