of rated current. The compensation below 5% and above 100% is constant and linear inbetween, see figure 245.Phase currents (magnitude and angle) are available on the outputs and each magnitudeoutput has a corresponding supervision level output (Ix_RANGE). The supervisionoutput signal is an integer in the interval 0-4, see section "Measurement supervision".14.1.8.4 Phase-phase and phase-neutral voltage measurements VMMXU,VNMMXUThe voltage function must be connected to three-phase voltage input in the configurationtool to be operable. Voltages are handled in the same way as currents when it comes toclass 0.5 calibrations, see above.The voltages (phase or phase-phase voltage, magnitude and angle) are available on theoutputs and each magnitude output has a corresponding supervision level output(Vxy_RANG). The supervision output signal is an integer in the interval 0-4, see section"Measurement supervision".14.1.8.5 Voltage and current sequence measurements VMSQI, CMSQIThe measurement functions must be connected to three-phase current (CMSQI) or voltage(VMSQI) input in the configuration tool to be operable. No outputs, other than X_RANG,are calculated within the measuring blocks and it is not possible to calibrate the signals.Input signals are obtained from the pre-processing block and transferred to correspondingoutput.Positive, negative and three times zero sequence quantities are available on the outputs(voltage and current, magnitude and angle). Each magnitude output has a correspondingsupervision level output (X_RANGE). The output signal is an integer in the interval 0-4,see section "Measurement supervision".14.1.9 Technical dataTable 375:CVMMXN, CMMXU, VMMXU, CMSQI, VMSQI, VNMMXUFunction Range or value AccuracyVoltage (0.1-1.5) ×Vn ± 0.5% of Vn at V£Vn± 0.5% of V at V > VnConnected current (0.2-4.0) × In ± 0.5% of In at I £ In± 0.5% of I at I > InActive power, P 0.1 x Vn< V < 1.5 x Vn0.2 x In < I < 4.0 x In± 1.0% of Sn at S ≤ Sn± 1.0% of S at S > SnTable continues on next page1MRK 502 048-UUS A Section 14Monitoring537Technical manual
