Section 7 1MRS758407 B Measurement functions Section 7 Measurement functions Basic measurements 7.1.1 Functions The three-phase current measurement function CMMXU is used for monitoring and metering the phase currents of the power system. The three-phase voltage measurement function VMMXU is used for monitoring and metering the phase-to-phase voltages of the power system.
Page 178
Section 7 1MRS758407 B Measurement functions Some of the measurement functions operate on two alternative measurement modes: "DFT" and "RMS". The measurement mode is selected with the X Measurement mode setting. Depending on the measuring function if the measurement mode cannot be selected, the measuring mode is "DFT".

Section 7 1MRS758407 B Measurement functions In the three-phase voltage measurement function VMMXU the supervision functions are based on the phase-to-phase voltages. However, the phase-to-earth voltage values are also reported with the phase-to-phase voltages. GOOSE is an event based protocol service. Analog GOOSE uses the same event generation functions as vertical SCADA communication for updating the measurement values.
