Power and automation technology group ABB has won an order from Italian utility Azienda Comunale Elettricita e Acque to supply medium-voltage products that will help facilitate the development of a smart grid project spanning a new section of Rome's electrical distribution network.

As part of the order, ABB says it will provide its UniSec switchgear equipped with protection relays from the Relion product family. The company reports that the switchgear was specifically developed for smart grid applications and has combined current and voltage sensors for use in secondary substations.

The UniSec switchgear, ABB notes, also includes devices for primary substations and for interfacing with distributed generation in secondary distribution substations.

According to ABB, the two companies have already been working together on initial experiments based on sections of Rome's electrical grid. The tests involved two primary substations, 76 secondary substations, four distributed generation plants, several customers connected at a medium-voltage level and around 1,200 low-voltage users.
