In response to the increased request for customers protection and quality improvements, an innovative system for wide-ranging power quality monitoring of Medium Voltage distribution networks was implemented in Italy. The main aim of the monitoring system is to provide a baseline of knowledge on the actual quality level in Italy and to enable the relevant regulatory actions in the interest of consumers. The monitoring system consists of 600 measurement units of Voltage Quality parameters (400 in MV-bars and 200 in Secondary Substations) and of a central system for data collection and storage. Privileged and public users can gain access and examine the results of the ongoing monitoring campaign through this website.
The 400 MV-bars have been subdivided proportionally to the number of MV networks (MV-bars) present in each Italian region in order to represent the different structures and environmental conditions of the Italian MV networks.

The owners of the measurement unit, MU, have access to the detailed results of measurement (time of occurrence and characteristics of any single disturbance) and to statistics of disturbances recorded by their MU over selected intervals of time. The access is made through a password that allows the non disclosure of proprietary information.

The public may access into the website and ask for processing and reporting of the data collected by the monitoring system aggregating the results in groups of MU.
