Description

In #5298, PhaseImpedanceData.fromPhase and PhaseImpedanceData.toPhase attributes have been removed. However, there is a use case for keeping those attributes, that is the use of line templates with electrical parameters. This is somewhat common on the distribution space. For example, find attached a screenshot of an Unbalanced line template in CYME where the entries of the matrix are specified using phases.

Proposed Solution

(Re)add PhaseImpedanceData.fromPhase and PhaseImpedanceData.toPhase attributes and update the description of PhaseImpedanceData class accordingly.

Decision

19-Sep-2024 Joint TF Hybrid Meetings:

After discussing it is clear that we will need Celso to sound off with an explanation as to why the row and column cannot be used (i.e. the original reason we removed from/to is due to the many different approaches to exchanging this data. We moved to remove them to reduce the number of options)

Celso, Chavdar and I added back in the attributes. However, the description will need your help to define. The issue is that we can not restore the old description at the Class level as it original was. This is due to reworking the class description for a separate Redmine Issue. Please review and touch base with us.
