The definition of a tie device has been updated for 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.
- The device can be fed on at least one phase by different ultimate sources or subsources (if the subsources reside on the same feeder level) on one side of the device compared to the other side. All subsources on both sides of the device must have the same feeder level in order to qualify for consideration.
- When you close the device, the network becomes fed on at least one phase by a different ultimate source or subsource.
 |
- 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.
