IfcElectricGeneratorType

Definition from IAI: An IfcElectricGeneratorType defines a particular type of engine that is a machine for converting mechanical energy into electrical energy.

HISTORY: New entity in IFC 2x2

Use Definitions,

An IfcElectricGeneratorType is a subtype of IfcEnergyConversionDeviceType that provides for all forms of electric engine.

Usage of IfcElectricGeneratorType defines the parameters for one or more occurrences of IfcEnergyConversionDevice. No predefined types of electrical generator are specified at this stage. Use the IfcElectricalGeneratorType.Name and IfcElectricalGeneratorType.Description attributes to further qualify a generator.

Property Set Use Definition:

The property sets relating to the IfcElectricGeneratorType are defined by the IfcPropertySet and attached by the IfcRelDefinesByType relationship. It is accessible by the inverse IsDefinedBy relationship. The following property set definitions specific to an IfcElectricGeneratorType are part of this IFC release:

Pset_ElectricalDeviceCommon: property set for properties that are common to all types of electrical devices, if available
Pset_ElectricGeneratorTypeCommon: property set for properties that are common to all types of electrical generator, if available

Geometry Use Definitions

Representations of the type are defined as representation maps (at the level of the supertype IfcTypeProduct). These are assigned at the occurrence through the IfcShapeRepresentation.Item being an IfcMappedItem.
