Measurement functions

7.1

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. 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 sequence current measurement CSMSQI is used for monitoring and metering

the phase sequence currents.
The sequence voltage measurement VSMSQI is used for monitoring and metering

the phase sequence voltages.
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 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.
The information of the measured quantity is available for the operator both locally

in WHMI and remotely to a network control center with communication.

If the measured data in WHMI is within parentheses, there are some

problems to express the data.

7.1.2

Measurement functionality

The functions can be enabled or disabled with the

Operation setting. The

corresponding parameter values are "On" and "Off".
Some of the measurement functions operate on two alternative measurement

modes: "DFT" and "RMS". The measurement mode is selected with the

Measurement mode setting. Depending on the measuring function if the

measurement mode cannot be selected, the measuring mode is "DFT".
