In installati*** with 3rd harmonic generation loads, the current
through the neutral cable can be higher than the one in the pha-
ses, even in case of balanced loads. The most proper solution for
these problems is to use a specific equipment for the 3rd harmonic
filtering, c***isting basically in a three-phase isolating transformer,
delta-star connected, that filters the 3rd harmonic current, plus a
passive filter which reduces the 5th harmonic.
