Tie Devices and Feeder Manager 2.0
In order for Feeder Manager 2.0 to recognize a feature as a tie device, the feature must meet all of the following criteria:
- The feature must be an open, switchable device. For example, dynamic protective devices can be tie devices. Service points and transformers cannot. Any switchable device can be a tie device.
- A tie device may have different ultimate and subsources on a side, as long as the feeder level is the same on both sides of the device. A device with feeds coming from Feeder 1 and Feeder 2 on one side and Feeder 3 on the other side can be a tie device, as long as the feeder level for all three feeders is the same when it reaches the tie device.
- When you close the device, the network becomes fed on at
least one phase by a different ultimate source or subsource. NOTE:
Feeder Manager 2.0 considers all tie devices to be multi-fed.
Note that subsources feed, but do not energize, downstream features. Subsources themselves must be energized in order to be discovered by the Find Feeder tool.
