10 Most Electrical Wire Size Voltage Drop Collections - Dear sir the value of contemporary which you have used for calculating voltage drop is the current that an individual fixture required but before first pole the value of present day have to be 2.Nine*three=8.7 amps. Accurate me if i’m wrong pls. Thanks.
It's miles understood that for 3-section balanced circuits, the impartial current turns out to be 0, but the difficulty isn't always that at all. Considering that your vd is based on single segment, so going lower back to iec-60364, you have to use unmarried section components for calculating the single section vd. So, do revise your single phase vd calculation hence to fulfill with the code requirements of iec-60364 for the 1-segment vd of avenue lighting poles. You can not exchange the 1-section vd components.

Why vd for unmarried segment is two*i *l (rcos phi x sin phi ) ? Because the current move in line and go back in neutral so the full route is double length and we use 2 , nothe this is not the case we discuss.
