Theory & Design第 87 / 110 题
On a feeder with significant harmonic (nonlinear) load, the neutral conductor is treated as:
a.Not a current-carrying conductor
b.A half current-carrying conductor
c.A current-carrying conductor
d.An ignored conductor
解析
Where the major portion of the load is nonlinear, the neutral carries harmonic current and must be counted as a current-carrying conductor for adjustment.
