1) “ Measure Ia”
，
“Measure Ic” display the rms of the measuring current transformer phase A and phase C
current. If there is no phase B measurement, 0 is displayed “Measure Ib”.
2) Measurement Uab
，
Ubc
，
Uca have the same input terminal as protection voltage Uab
，
Ubc
，
Uca. However
the data are directly taken from special measurement module. “cosΦ” is power factor
3) Active power P is directly taken from special measurement module.
4.18.3 Power measurement
This device applies two-meter-method to measure power. The direction of reactive power Q is decided by
corresponding angle of protection line voltage and current.
Therefore, when examining reactive power, phase A and phase C protection current must be connected
simultaneously.
