7.8.4.35 Pset_CurrentInstrumentTransformer

PSET_TYPEDRIVENOVERRIDE / IfcFlowInstrument / AMMETER,IfcFlowInstrument / COMBINED

Instrument transformers are high accuracy class electrical devices used to isolate or transform voltage or current levels. The main function of instrument transformers is to operate instruments or metering from high voltage or high current circuits, safely isolating secondary control circuitry from the high voltages or currents. Combination instrument transformers are metering current.

NameTypeDescription
AccuracyClass P_SINGLEVALUE / IfcRatioMeasure A designation assigned to an instrument transformer the current (or voltage) error and phase displacement of which remain within specified limits under prescribed conditions of use (IEC 321-01-24).
AccuracyGrade P_SINGLEVALUE / IfcLabel The grade of accuracy.
RatedVoltage P_BOUNDEDVALUE / IfcElectricVoltageMeasure
Rated VoltageThe range of allowed voltage that a device is certified to handle. The upper bound of this value is the maximum.
NominalCurrent P_SINGLEVALUE / IfcElectricCurrentMeasure
Nominal CurrentThe nominal current that is designed to be measured.
NominalPower P_SINGLEVALUE / IfcPowerMeasure A conventional value of apparent power determining a value of the rated current that may be carried with rated voltage applied, under specified conditions. ( IEV ref 421-04-04)
NumberOfPhases P_SINGLEVALUE / IfcCountMeasure Number of phases that the equipment operates on.
PrimaryFrequency P_SINGLEVALUE / IfcFrequencyMeasure
Primary FrequencyThe frequency that is going to be transformed and that runs into the transformer on the primary side.
第1周波数変圧器の1次側に伝送される周波数。
PrimaryCurrent P_SINGLEVALUE / IfcElectricCurrentMeasure
Primary CurrentThe current that is going to be transformed and that runs into the transformer on the primary side.
第1電流変圧器の1次側に伝送される電流。
SecondaryFrequency P_SINGLEVALUE / IfcFrequencyMeasure
Secondary FrequencyThe frequency that has been transformed and is running out of the transformer on the secondary side.
第2周波数変圧器の2次側に出力される周波数。
SecondaryCurrent P_SINGLEVALUE / IfcElectricCurrentMeasure
Secondary CurrentThe current that has been transformed and is running out of the transformer on the secondary side.
第2電流変圧器の2次側へ出力される電流。
