Dear All,
i Have this issue
i have experience on Power Meter Commissioning (using PM5000 series, ie pm5300 and 5500) like this :
- i had install metering normally (input voltage RSTN is correct and input CT RST and +- is correct), but the meter read leading power factor, and when i see the phase angle degree it says V1-A1= 306 degree, V2-A2= 30 degree, and V3-A3=306 degree which means it may be the Phase sequence must be rotated and CT must be inverted (if we see from phasor diagram based on angle degree that we have)
- when i do wiring correction (Phase Shifting and CT inverting) the meter read is ok (sistem is lagging), but it is not correct if we see by the wiring (i mean, now after correction input voltage R meets CT input phase S, input voltage S meet CT phase T, and input voltage T meet CT phase R), however the reading is good/ok
how about that ?
can anyone explain it ?
