Description

The following new Datatype should be added to Grid/Base/Domain/GeneralDatatypes

Class name: <CIMDatatype>MassPerLength
Note: (old) Mass per length. Enables specification of weight without details of the cross-section.
Note (New): Mass per length. It shall be a positive value or zero.
unit:InitalValue: kgPerm

Justification:
MassPerLength is used in specifying the weight of a cable independents of the length. This is needed for catalogue data for cable and wires.

Class name: <CIMDatatype>Force
Note: Force in newtons (kg·m/s²). It shall be a positive value or zero.
unit:InitalValue: N

Justification:
Force is used in specifying the maximum pull force that a cable can withstand.

Proposed Solution

The following new Datatype should be added to Grid/Base/Domain/GeneralDatatypes

Class name: <CIMDatatype>MassPerLength
Note: (old) Mass per length. Enables specification of weight without details of the cross-section.
Note (New): Mass per length. It shall be a positive value or zero.
unit:InitalValue: kgPerm

Justification:
MassPerLength is used in specifying the weight of a cable independents of the length. This is needed for catalogue data for cable and wires.

Class name: <CIMDatatype>Force
Note: Force in newtons (kg·m/s²). It shall be a positive value or zero.
unit:InitalValue: N

Justification:
Force is used in specifying the maximum pull force that a cable can withstand.


Decision

29-Nov-2023 - discussed during weekly WG13 modeling call:

Agreed to apply the proposed additions to the CIM with one additional change from what is stated in the Proposed Solution:

For Force:
Note: "Force in newtons (kg·m/s²). It shall be a positive value or zero."

Should be...
Note: "Force in newtons. It shall be a positive value or zero."

Release Notes

- Added <CIMDatatype>MassPerLength, Note: Mass per length. It shall be a positive value or zero.
unit:InitalValue: kgPerm
- Note the multiplier of the datatype is set to none
- added new UnitSymbol kgPerm with the note "Mass per length in kilogram/metres (kg/m). Note: multiplier “k” is included in this unit symbol for compatibility with mass datatype."
- added <CIMDatatype>Force Note: Force in newtons. It shall be a positive value or zero.
unit:InitalValue: N
