Electrical losses calculation under nonideal conditions: Computational versus experimental analysis

The aim of this paper is to analyze the additional electrical losses in resistors subjected to non-ideal conditions of operation, ie, harmonic currents. With respect to the traditional ways to calculate the additional losses question, the analysis presented in this work is done in order to differentiate an increase of losses due to an increase in the RMS value and due to the current distortion waveform. Thus, in this paper, this analysis is based on both computer simulations and in laboratory measurements of the resistor temperature. The results from these two analysis tools are compared and confronted each other.
