Measuring system for distorted regime generated by three phase nonlinear loads

In scope of studying the distorted regime parameters generated by three phase nonlinear loads, this paper presents a measuring system that uses LabVIEW. Using a data acquisition board connected to a computer, the proposed system can acquire distorted and unbalanced current and voltage signals and processes them by a LabVIEW application in order to display the variation of the specified parameters. This measuring system permits for the electrical parameters to be observed in real time, being very important in studying the nonlinear loads functioning. As well, this paper contains the variations of the electrical parameters that are measured using described system.
