It is possible to calibrate the measuring function above to get better then class 0.5presentation. This is accomplished by angle and amplitude compensation at 5, 30 and100% of rated current and at 100% of rated voltage.The power system quantities provided, depends on the actualhardware, (TRM) and the logic configuration made in PCM600.The measuring functions CMSQI and VMSQI provide sequence componentquantities:• I: sequence currents (positive, zero, negative sequence, amplitude and angle)• U: sequence voltages (positive, zero and negative sequence, amplitude andangle).16.1.3 Function blockThe available function blocks of an IED are depending on the actual hardware (TRM)and the logic configuration made in PCM600.CVMMXNI3P*U3P*SS_RANGEP_INSTPP_RANGEQ_INSTQQ_RANGEPFPF_RANGEILAGILEADUU_RANGEII_RANGEFF_RANGEIEC10000016-1-en.vsdIEC10000016 V1 ENFigure 411: CVMMXN function blockIEC05000699-2-en.vsdCMMXUI3P* IL1IL1RANGIL1ANGLIL2IL2RANGIL2ANGLIL3IL3RANGIL3ANGLIEC05000699 V2 ENFigure 412: CMMXU function block1MRK502052-UEN B Section 16Monitoring859Technical manual
