Model Electrical Circuit

Overview

Provides the information concerning electrical circuits.
An electrical circuit is a particular type of system. Specific detail about systems is given in the functional part fp_model_system to which reference should be made.
Note that for an electrical circuit, only certain instances of product types can be grouped into the system. These are shown below.

Results

Specification of the electrical circuit and the elements that are connected to it.
Setting of values for key properties of the electrical circuit.

Description	Entity/Pset/Functional Part	MAN	REC	OPT
Specify the electrical circuit occurrence in which elements will participate An electrical circuit is directly specified as an occurrence. It does not have a defining type entity.	IfcElectricalCircuit
Set the global unique identifier	IfcElectricalCircuit.GlobalId::IfcGloballyUniqueId
Assert the owner history of the system	IfcElectricalCircuit.OwnerHistory ::fp_apply_owner_history
Specify the name of the circuit. Although this is an optional attribute within IFC, it must be asserted for an electrical circuit.	IfcElectricalCircuit.Name::IfcLabel
Specify a description for the circuit Whilst the description does not add value to the semantics of the circuit, it can provide significant information for later project stages, particularly in terms of providing an insight into a designers intent that remains available at operating and maintenance stages of a project.	IfcElectricalCircuit.Description::IfcText
Specify the type of the system according to IEC 60364 type conventions. Note that this identification is not the same as the name or description of the circuit. Values that may be used for type include: TN type system, a system having one or more points of the source of energy directly earthed, the exposed conductive parts of the installation being connected to that point by protective conductors, *TN C* type system, a TN type system in which neutral and protective functions are combined in a single conductor throughout the system, *TN S* type system, a TN type system having separate neutral and protective conductors throughout the system, *TN C S* type system, a TN type system in which neutral and protective functions are combined in a single conductor in part of the system, TT type system, a system having one point of the source of energy directly earthed, the exposed conductive parts of the installation being connected to earth electrodes electrically independent of the earth electrodes of the source, IT type system, a system having no direct connection between live parts and Earth, the exposed conductive parts of the electrical installation being earthed.	IfcElectricalCircuit.ObjectType ::IfcLabel
Define the property set(s) for system The entity for which the property set is defined is IfcElectricaalCircuit whilst the property set defined is Pset_Asset	fp_define_by_properties
Specify the elements that are to participate in the circuit. Note that, for a system generally, a WHERE rule is applied that constrains the related objects to be subtypes of IfcElement For an electrical circuit, the elements that can be connected are defined in the occurrence/type list below: for instances that are IfcEnergyConversionDevice IfcElectricGeneratorType IfcElectricMotorType IfcTransformerType for instances that are IfcFlowTerminal IfcElectricApplianceType IfcElectricHeaterType IfcLightFixtureType IfcOutletType for instances that are IfcFlowController IfcElectricTimeControlType IfcProtectiveDeviceType IfcSwitchingDeviceType IfcElectricDistributionBoardType for instances that are IfcFlowSegment IfcCableType for instances that are IfcFlowFitting IfcJunctionBoxType for instances that are IfcFlowStorageDevice IfcElectricFlowStorageDeviceType for instances that are IfcDistributionControlElement IfcProtectiveDeviceTrippingUnitType	IfcElement<subtype>
Note that there is no specific placement or shape representation of a circuit. The actual placement and shape is determined by the products that participate in the system. Placement and shape representation are only relevant for a system where it is to be visually represented.	IfcElement.ObjectPlacement::fp_place_object IfcElement.Representation::fp_represent_product
Assert the relationship that assigns the set of elements that will participate in the circuit This is defined in a separate functional part	fp_assigns_to_group
Assert the relationship between a circuit and a spatial structure element (site, building, storey, space) that it services This is defined in a separate functional part	fp_services_building
Set additional information about the circuit
Set the ratio of the simultaneous maximum demand of a group of electrical appliances or consumers within a specified period, to the sum of their individual maximum demands within the same period. The group of electrical appliances is in this case connected to the electrical circuit in question. It is often not desirable to size each conductor in a distribution system to support the total connected load at that point in the network. Diversity is applied on the basis of the anticipated loadings that are likely to result from all loads not being connected at the same time. Diversity is applied to final circuits only, not to sub-main circuits supplying other distribution boards.	Pset_ElectricalCircuit.Diversit::IfcPropertySingleValue::IfcPositiveRatioMeasure
Set the number of phases within this circuit. Either this property or the PhaseReference property (if only one) may be asserted.	Pset_ElectricalCircuit.NumberOfPhases?IfcPropertySingleValue::IfcInteger
Set the maximum voltage drop across the circuit that must not be exceeded. There are two voltage drop limit settings that may be applied; one for sub-main circuits, and one in each Distribution Board or Consumer Unit for final circuits connected to that board. The settings should limit the overall voltage drop to the required level. Default settings of 1.5% for sub-main circuits and 2.5% for final circuits, giving an overall limit of 4% may be applied. This value may also be specified as a constraint within an IFC model if required but is included within the property set at this stage pending implementation of the required capabilities within software applications.	Pset_ElectricalCircuit.MaximumAllowedVoltageDrop::IfcPropertySingleValue::IfcElectricVoltageMeasure
Set the maximum earth loop impedance upstream of a circuit. This is typically stated as the variable Zs. This value is for 55o C (130oF) Celsius usage.	Pset_ElectricalCircuit.NetImpedance::IfcPropertySingleValue::IfcElectricResistanceMeasure
Set the type of function for which the conductor is intended. Note that only one value shall be allowed for each conductor Allowed values within the enumeration are: Phase_L1 Phase_L2 Phase_L3 Neutral ProtectiveEarth ProtectiveEarthNeutral Other NotKnown Unset L1, L2 and L3 represent the phase conductors according to IEC 60446 notation (sometimes also by color [Red, Blue, Yellow] or by number [1, 2, 3] etc). Protective Earth Neutral is sometimes also known as CPC or common protective conductor.	Pset_ElectricalCircuit.ConductorFunction::IfcPropertyEnumeratedValue::PEnum_ConductorFunctionEnumbq.
