saturation often shows in a flattened voltage wave shape. If the
positive voltage half-cycle is a different shape than the negative
half-cycle, even-order voltage harmonics are present. Often the
current waveforms will not be sinusoidal. The less they look like a
sine wave, the higher the level of current harmonics. Frequently,
the neutral current looks much less sinusoidal than the line
currents, because some harmonics do not cancel out in a three-
phase system, even with a balanced load. The more the current
waveform is shifted from the voltage waveform, the worse the
power factor.
