Quality analysis of electric energy using an interface developed in LabVIEW environment

This paper presents a case study for monitoring the quality of electric energy in an industrial consumer. The measurements were carried in the power supply point and the data processing was achieved using LabVIEW software. It was made an interface to allow reading of files and processing them (creation of data tables and charts). Based on the data obtained from the measurements and using the interface created in LabVIEW, it was possible to carry out the analysis of the average hourly consumption, the power factor, the wave forms of the current and voltage, the analysis of the current and voltage harmonics. Using an interface developed in LabVIEW, full quality analysis of electric energy can be done at the user's premises.
