A Distributed Web-Based System for Temporal and Spatial Power Quality Analysis

A distributed web-based system for temporal and spatial power quality analysis has been realized and tested. Connecting by internet local instruments able to perform high accuracy measurements in real time, the Power Quality information, locally measured, can be sent to a remote central server which aim is to plot them and stored the data for future analysis. The remote instruments have been realized, tested and placed in two Italian cities, Palermo and Rome, where actually work while the server works in Rome. The web application allows to select the single instrument and to show its stored PQ information

Perceived Power Quality

The problem discussed in this chapter relate directly to the economic, sociological and psychological aspects of, and also the scientific-technical elements connected with electric power production, distribution and fruition. For this reason, only the international rules connected with the technical, economic and environmental fields will be considered, if possible, working in the industrial world. These are the set of ISO 9000 rules for the quality that will influence the ISO 14000 rules for the environment (not discussed here)
