Phase currents (amplitude and angle) are available on the outputs and eachamplitude output has a corresponding supervision level output (ILx_RANG). Thesupervision output signal is an integer in the interval 0-4, seesection "Measurement supervision".10.1.7.4 Phase-phase and phase-neutral voltage measurements VMMXU,VNMMXU SEMOD54417-268 v6The voltage function must be connected to three-phase voltage input in theconfiguration tool to be operable. Voltages are handled in the same way as currentswhen it comes to class 0.5 calibrations, see above.The voltages (phase-to-earth or phase-to-phase voltage, amplitude and angle) areavailable on the outputs and each amplitude output has a corresponding supervisionlevel output (ULxy_RANG). The supervision output signal is an integer in theinterval 0-4, see section "Measurement supervision".10.1.7.5 Voltage and current sequence measurements VMSQI, CMSQISEMOD54417-299 v6The measurement functions must be connected to three-phase current (CMSQI) orvoltage (VMSQI) input in the configuration tool to be operable. No outputs, otherthan X_RANG, are calculated within the measuring blocks and it is not possible tocalibrate the signals. Input signals are obtained from the pre-processing block andtransferred to corresponding output.Positive, negative and three times zero sequence quantities are available on theoutputs (voltage and current, amplitude and angle). Each amplitude output has acorresponding supervision level output (X_RANGE). The output signal is aninteger in the interval 0-4, see section "Measurement supervision".10.1.8 Technical dataM12386-1 v16Table 305:Power system measurement CVMMXN technical dataFunction Range or value AccuracyFrequency (0.95-1.05) x fr ±2.0 mHzVoltage (10 to 300) V ±0.3% of U at U≤ 50 V±0.2% of U at U> 50 VCurrent (0.1-4.0) x Ir ±0.8% of I at 0.1 x Ir< I < 0.2 x Ir± 0.5% of I at 0.2 x Ir< I < 0.5 x Ir±0.2% of I at 0.5 x Ir< I < 4.0 x IrActive power, P (10 to 300) V(0.1-4.0) x Ir±0.5% of Sr at S ≤0.5 x Sr±0.5% of S at S > 0.5 x Sr(100 to 220) V(0.5-2.0) x Ircos φ> 0.7±0.2% of PTable continues on next pageSection 10 1MRK 511 424-UEN BMonitoring384 Bay control REC650 2.2 IECTechnical manual
