D’ANNA E BONACCORSI ELECTRICITY COMPANY (USTICA - PA) Checking electrical parameters and recording data relating to the consumption of individual users.

Electrical parameter control and data acquisition related to individual user consumption from Landis concentrators, for the substations via radio communication, thanks to the creation of a 5.2 GHz WLAN network that covers the entire island. The system completely replaces the GSM communication module from individual concentrators, allowing the client to save approximately 8,000-10,000 euros per year in mobile phone expenses. Furthermore, both the internal temperature of the substations and the temperature of the transformers themselves are monitored, alerting personnel through visual and acoustic signals and email notifications in case of specification violations. The monitored values are: Actual and maximum current, Actual and minimum voltage, Active and Reactive Power, Phase shift, Sum of currents on a single line for each substation. All data is graphically represented with the ability to recall data from even very distant periods using time-scroll buttons. Remote download of data sampled by individual analyzers is possible. The system automatically sends daily reports via email containing alarms and verified anomalies from the previous 24 hours. The system is based on a webserver platform, so it's possible to access both the graphical supervision interface, where the system status can be checked, and an interface for consulting recorded data via CSV file access from any browser.
