The measurement & Analysis of Voltage Unbalance Factor at LV Customer of Three-Phase Four-Wire System
3상 4선식 저압 수용가의 전압 불평형율 측정분석

Abstract
Most of LV customer has been composed the 3-phase four wire system distribution system which is supplying simultaneously at the 1-phase & 3-phase load. In this system, the composition of the power apparatus system is simple rather than conventional separation mode of the 1-phase & 3-phase, But due to uneven load unbalance or unclean power quality, various kinds such as do-rating or power losses become an issue. In this paper, we measured and analyzed voltage and current waveform in the field, compared with internationally allowable voltage unbalance limits.
