This paper is about the design of a power quality monitoring system based on LabVIEW for factory power quality defined in the IEEE Standard 1459-2010 for single-phase, three phase three-wire and three-phase four-wire power systems. With LabVIEW as development platform, composed by some functional modules such as data acquisition, data processing, data storage, and data report, etc. defined in International standards concerning electrical power quality Standard EN 50160. This system has

The virtual instrument developed through the front panel, graphical user interface (GUI) provides analysis functions according to the standard EN 50160: Magnitude of the supply voltage and Current, frequency, the phasors diagrams for voltage and current [10], Voltage and Current harmonics, voltage unbalance. And other analysis conforms to the IEEE Standard 1459-2010: real and reactive power, energy use, power factor and frequency etc. [1,2]. The system was tested and calibrated in laboratory provides continuous monitoring of a three-phase system, with resistive, inductive and capacitive loads (Figures 4-8) .
