With the exception of the incandescent light bulb, every load today creates harmonics. Unfortunately, these loads vary with respect to their amount of harmonic content and response to problems caused by harmonics.

how harmonic current can be measured
Why are triplen harmonics more dangerous than other harmonics?
triplen harmonics means unbalance between the phases. Obvisously unbalance in three phases causes neutral current (Ia+Ib+Ic).
In Ideal three phase systems, for balaned 3 phases, no neutral current.
