• I: phase currents (magnitude and angle) (CMMXU)• V: voltages (phase-to-ground and phase-to-phase voltage, magnitude and angle)(VMMXU, VNMMXU)The CVMMXN function calculates three-phase power quantities by using fundamentalfrequency phasors (DFT values) of the measured current and voltage signals. Themeasured power quantities are available either, as instantaneously calculated quantitiesor, averaged values over a period of time (low pass filtered) depending on the selectedsettings.It is possible to calibrate the measuring function above to get better then class 0.5presentation. This is accomplished by angle and magnitude compensation at 5, 30 and100% of rated current and at 100% of rated voltage.The power system quantities provided, depends on the actual hardware,(TRM) and the logic configuration made in PCM600.The measuring functions CMSQI and VMSQI provide sequence component quantities:• I: sequence currents (positive, zero, negative sequence, magnitude and angle)• V: sequence voltages (positive, zero and negative sequence, magnitude and angle).16.1.3 Function block SEMOD130334-4 v7The available function blocks of an IED are depending on the actual hardware (TRM)and the logic configuration made in PCM600.1MRK 511 408-UUS A Section 16MonitoringPhasor measurement unit RES670 2.2 ANSI 489Technical manual
