A 3-phase, 4-wire, wye-connected power system supplying nonlinear loads may necessitate a design allowing for the possibility of ____ on the neutral conductor.
A) transient arching
B) low harmonic neutral currents
C) excessive heat
D) high harmonic neutral currents

Question

Quizplus · Accepted Answer

Nonlinear loads can cause harmonic distortion in the system, including the potential for high harmonic currents on the neutral conductor. This can lead to overheating of the neutral conductor, which could cause damage or even a safety hazard. Therefore, the design should account for the possibility of high harmonic neutral currents.
