Pset_CurrentInstrumentTransformer 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. IfcFlowInstrument/AMMETER IfcFlowInstrument/COMBINED IfcFlowInstrument/AMMETER,IfcFlowInstrument/COMBINED AccuracyClass 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 The grade of accuracy. RatedVoltage The range of allowed voltage that a device is certified to handle. The upper bound of this value is the maximum. Rated Voltage NominalCurrent The nominal current that is designed to be measured. Nominal Current NominalPower 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 Number of phases that the equipment operates on.
