Internet based measurement and analysis of power quality

In this study, internet based measurement and analysis of power quality has been realized. In the system current and voltage are measured using a measurement board and then measured values are transferred to the computer via simultaneous data acquisition board. Transmission of the data from data acquisition board to the computer and real-time analysis of them are achieved using software written in LabVIEW. With developed software voltage, current and power waveforms of the power system can be seen; voltage and current harmonic values are calculated and then plotted on the computer screen. Measured and analyzed values are transferred to the internet via web publishing tool. In order to obtain internet based power quality monitoring system. Any user who wishes to remote monitoring of the system can connect using every computer that has internet connection and realized measurement and analysis in real time. With the implemented system, useful, updatable, and low cost power quality measurement system has been obtained.
