Harmonic Analysis in Functioning of Nonlinear Loads

摘要

Present paper studies the current harmonic spectrum generated by functioning of an electrothermal installation with electromagnetic induction. In order to analyze the electrical parameters that characterize the electrothermal installation functioning, measurement sets were accomplished using two methods. The first method consists in using a power and energy quality analyzer and the second method uses an acquisition system that contains an adapting interface and a data acquisition board connected to a computer. Paper contains also a simulation of the electrothermal installation functioning realized in PSCAD-EMTDC.
