There are two associations defined at ConductingEquipment level and inherited by the concrete ConductingEquipment classes, i.e. Equipment.EquipmentContainer and ConductingEquipment.BaseVoltage. These two associations are optional by default, i.e. with cardinality 0..1 specified  at the ConductingEquipment side. However, these two associations may be required for some concrete  ConductingEquipment classes, even though the  cardinality specification is shown as 0..1 in the profile. More specifically, ConductingEquipment.BaseVoltage is required for class ACLineSegment, EquivalentBranch and SeriesCompensator and optional for any other concrete ConductingEquipment classes.<br /></p><p>Equipment.EquipmentContainer is required for any concrete ConductingEquipment classes other than ACLineSegment and SeriesCompensator. <br /></p><p> <br /></p><p>Reason: ACLineSegment and SeriesCompensator may not be contained. Thus, it is necessary to specify BaseVoltage. Other ConductingEquipments (except PowerTransformer) are normally contained by VoltageLevel, thus there is no need to specify the BaseVoltage for them. BaseVoltage is specified at PowerTransformerEnd for PowerTransformer<br /></p>
