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. The phase-to-earth voltages are also available in VMMXU.
The residual current measurement function RESCMMXU is used for monitoring and metering the residual current of the power system.
The residual voltage measurement function RESVMMXU is used for monitoring and metering the residual voltage of the power system.
The sequence current measurement function CSMSQI is used for monitoring and metering the phase sequence currents.
The frequency measurement FMMXU is used for monitoring and metering the power system frequency.
The three-phase power and energy measurement PEMMXU is used for monitoring and metering the active power (P), reactive power (Q), apparent power (S) and power factor (PF) and for calculating the accumulated energy separately as forward active, reversed active, forward reactive and reversed reactive. PEMMXU calculates these quantities using the fundamental frequency phasors, that is, the DFT values of the measured phase current and phase voltage signals.
