Abstract

Each type of device causing harmonics has a particular shape of harmonic current and voltage (amplitude and phase displacement). This work provides a methodology for analyzing the distortion from the data record of digital fault recorders in order to quantify the distortion in current and voltage. This can be done by decomposing the signal into its constituent components in the frequency domain, because of the fact that it is not practical to obtain and represent all the system detail for analysis. It can lead to inaccurate estimation of distortion in voltages and currents. A simple but realistic approach for resonance analysis is presented.
