: public Ifc4x3_rc1::IfcEnergyConversionDevice¶ A transformer is an inductive stationary device that transfers electrical energy from one circuit to another. IfcTransformer is used to transform electric power; conversion of electric signals for other purposes is handled at other entities: IfcController converts arbitrary signals, IfcAudioVisualAppliance converts signals for audio or video streams, and IfcCommunicationsAppliance converts signals for data or other communications usage.
HISTORY New entity in IFC2x4
Type Use Definition IfcTransformer defines the occurrence of any transformer; common information about transformer types is handled by IfcTransformerType. The IfcTransformerType (if present) may establish the common type name, usage (predefined type), properties, materials, ports, composition, assignments, and representations. The IfcTransformerType is attached using the IfcRelDefinesByType objectified relationship and is accessible by the IsTypedBy inverse attribute. If the IfcTransformerType has ports or aggregated elements, such objects are reflected at the IfcTransformer occurrence using the IfcRelDefinesByObject relationship.
Property Use Definition The property sets relating to this entity are defined by IfcPropertySet and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute. Property sets may also be specified at the IfcTransformerType, defining the common property data for all occurrences of the same type. They are then accessible by the IsTypedBy inverse attribute pointing to IfcTransformerType.HasPropertySets. If both are given, then the properties directly defined at IfcTransformer override the properties defined at IfcTransformerType. Refer to the documentation at the supertype IfcEnergyConversionDevice and ancestors for inherited property set definitions. The following property set definitions are applicable to this entity: Pset_TransformerTypeCommon (PSET_TYPEDRIVENOVERRIDE)
Quantity Use Definition The quantities relating to this entity are defined by IfcElementQuantity and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute. The following base quantities are defined and shall be exchanged with the IfcElementQuantity.Name = ‘BaseQuantities’. Other quantities, being subjected to local standard of measurement, may be defined with another string value assigned to Name. In this case a valid value for MethodOfMeasurement shall be provided.
Qto_TransformerBaseQuantities
Material Use Definition The material of the IfcTransformer is defined by IfcMaterialConstituentSet or as a fallback by IfcMaterial, and attached by the RelatingMaterial attribute on the IfcRelAssociatesMaterial relationship. It is accessible by the HasAssociations inverse attribute. Material information can also be given at the IfcTransformerType, defining the common attribute data for all occurrences of the same type. The following keywords for IfcMaterialConstituentSet.MaterialConstituents[n].Name shall be used:
Casing: Material from which the casing is constructed.
Port Use Definition The distribution ports relating to the IfcTransformer are defined by IfcDistributionPort and attached by the IfcRelConnectsPortToElement relationship. If the transformer occurrence is defined by IfcTransformerType, then the port occurrences must reflect those defined at the IfcTransformerType using the IfcRelDefinesByObject relationship. Ports are specific to the IfcTransformer PredefinedType as follows indicated by the IfcDistributionPort Name, PredefinedType, and FlowDirection:
Line (ELECTRICAL, SINK): Line to be transformed. Load (ELECTRICAL, SOURCE): Transformed load.
