The first current and voltage phase in the group signals will be used as reference and the
amplitude and angle compensation will be used for related input signals.
Analog outputs from the function can be used for service values or in the disturbance report. The
active power is provided as MW value: P, or in percent of base power: PPERCENT. The reactive
power is provided as Mvar value: Q, or in percent of base power: QPERCENT.
