Well in an industry or a home's installation, the phases are get with a neutral wire which it's the wire attached in the transformer's center star and that point is put at ground (literaly). Due the current armonic distortion, the neutral can has a potential with respect ground. What value can get that differential potential? I know that if there is resonation it can have more than 220V. There is a table of it? The odd armonic in neutral are the problem here. What voltage peak can be?
