Description

The current BusBarSection class is a single terminal ConductingEquipment that represents where the physical busbar is in the substation.
In a recent use case presented from SaskPower (by Chuck and jointly with Judy), the busbar construction could be phased and different materials might be used among phases.
This will lead to a single busbar with multiple ratings (flow & voltage) and in a practical power-flow study, they would be modeled as multiple buses in order to report violations properly.

Proposed Solution

Chuck has presented a proposal on BusSegment as a two-terminal ConductingEquipment to 'separate' the single busbar into multiple pieces.
Details can be found as attached.

Decision

19-Sep-2024 Joint TF Hybrid Meetings - Minneapolis:
Reviewed. The following is needed:

- AI: Add required information to the 301 template.
- AI: Ensure it is in the 452 template.
- AI: Have agreed to take the normalRetained (in the -452) and retained (in the -456) approach to Switch and BusSegment
