One of the power companies in the north-eastern United States recently established an Ethernet network that extended to the substation level. The network was put into place with the goal of gathering real-time power metering data from its group of substations.
The company needed to Ethernet-enable an installed base of Automatic Meter Reading (AMR) equipment and digital meters. Digi technology from Dominion Electronics provided an ideal solution for this power company.
Each meter from a substation connects to a router at the substation. In turn, the AMR receivers and digital meters are connected to a Digi solution, which makes them available for readings over the Ethernet.
Since the power company's Supervisory Control and Data Acquisition (SCADA) system would eventually be moved to the Ethernet as well, the customer requested a solution that would also support relays, power quality devices, circuit breakers, transformers and other intelligent electronic devices.
Network-enable existing serial devices and provide for system updates with a future-proof design.
