Description

The ability to link phase to position is provided by the changes to 61968 classes described in Issue #5295- Joint issue on ACLineSegment physical modeling clarification. This obviates the need for the .fromPhase and .toPhase attributes of the PhaseImpedanceData class.

Proposed Solution

The following is proposed:

PhaseImpedanceData – Delete the .fromPhase and .toPhase attributes as they are now redundant. Phase identification is supplied by either the ACLineSegmentPhase class or the WirePosition class and is referenced via the PhaseImpedanceData.row and .column attributes which map to either ACLineSegmentPhase.sequenceNumber or WirePosition.sequenceNumber.


Decision

20-Sep-2023: Decision is to apply these changes. The Joint Redmine issue that this WG13 issues is associated with was reviewed in full details in the Sept 6 and 13th meetings.

See attached 2020-01-30 Device Datasheet ACLineSegment requested UML updates.docx for details.
