That is not universally true. If you go line to line and not line to
neutral, then the third harmonic voltage, assuming symmetrical drive and
loading, there will be no line to line voltage at the third harmonic.

Clarify your question- are you dealing with a transformer? Then it will
depend on the connections on both sides including grounding. Ground or a
delta winding provides a path for triplen harmonic currents. Transformers
are the major source of triplen harmonics.
