Hormonics 3-phase

[george t. everett]

Do harmonics caused by non-linear loads cause aproblem on all three phase services or only on wye services?

Re: Hormonics 3-phase

Harmonics are a problem on all AC electrical systems.

The self generated current is more apparent on a wye neutral due to being in the same time domain as the load current.

George, wye configurations are the real sufferers. A center tapped delta would see the same scenario as a center tapped single phase (single winding) transformer.
