The Distribution Systems table defines distribution systems that are available in your project.
- Name - A unique name that identifies a distribution system.
- Phase - Either Three or Single, selected from the drop-down list
- Configuration - After you click the value, you can select Wye or Delta, from the drop-down list (three-phase systems only).
- Wires - This parameter specifies to the number of conductors (3 or 4 for three-phase, 2 or 3 for single-phase).
- L-L Voltage - After you click the value, you can select a Voltage Definition that represents the voltage measured between any two phases. The specification of this parameter depends on the Phase and Wire selections. For example, L-L Voltage is not applicable for a single-phase, 2-wire system.
- L-G Voltage - After you click the value, you can select a Voltage Definition that represents the voltage measured between a phase and ground. L-G is always available.
Note: Although this table allows you to specify a distribution system with a Configuration value of Delta and a Wire value of 4, this type of system (High, Red, or Wild leg) is currently not supported in Revit because there is no way to specify the high leg voltage.
Click Add and enter parameters to specify a new distribution system. Click Delete to remove a selected distribution system. You cannot delete a distribution system that is currently assigned to a device in a project.
