Abstract

Recently reported results give measurements of the resistance and inductance of power cables and transformers vs. frequency. In harmonics analysis computer programs, various methods, including linear and exponential approximations and eddy current factors are used to model the increase of resistance with frequency, while the inductance is assumed to be constant. The measured results from the paper of Rhode, Kelley and Saran (1996) are used in this paper to evaluate the accuracy of various models
