4. Interface Connections: Connect the required interface cables between the bridge and the
RTU.
Bridges can also connect to voltage, capacitor, tap changer and VAR management controllers,
which usually provide their own serial and Ethernet ports. The eBridge or sBridge must be
installed in the same enclosure as the controller.
Types of Bridge Deployments
RTUs are key components of the electrical system that act as collection points for sensor data and
issue simple commands to control relays, regulators and other electrical system distribution
devices. After installation, the bridges bring the RTUs into a new Distribution Automation (DA)
network. Figure 4 shows a highly simplified example.
