Raleigh, North Carolina, United States, February 3, 2009 Elster and SensorLink Announce Successful Completion of Field Trials for Low Voltage AGInode

Elster, a leader in smart metering and smart grid systems and solutions, today announced the successful completion of field trials for its low voltage AGInode™. The low voltage AGInode, incorporating SensorLink’s advanced sensing technology, is a metering and monitoring device for low voltage overhead and underground transformers. Pilot installations were performed with utilities in Canada, the United States, and Latin America.

The low voltage AGInode is one of the first products resulting from Elster’s Advanced Grid Infrastructure (AGI) Initiative, a collaborative effort between utilities, Elster, and key technology providers to realize innovative solutions for grid modernization.

“Our utility customer field trials provided us with real-world feedback and have allowed us to refine the AGInode technology. The AGInode will be an effective tool for applications such as loss detection, voltage profiling, and transformer monitoring, and provides increased business benefits for utilities deploying Elster’s smart grid solutions,” said Carl LaPlace, Elster senior product manager.

“Our low voltage sensor technology allows the utility to easily install additional measurement nodes at key distribution points along the utility’s power system,” said Gary Hielkema, SensorLink president. “This project provides new opportunities for utilities to economically gather information from tactical grid locations to drive new applications for smarter grid management.”
