Hello excuse my i dont speak english well [Linked Image] I have problem with too big currents in the neutral wire of Zig-Zag-y grounding transformer. To the neutral wire of transformer on the Z site connected is a coil and this is grounded. This coil function is compensation too big capacitive currents but it not help too well. (How can I past a picture here?)

Gee Daniel, I don't know what to tell you. This might be a case where you should provide a drawing or pic of a drawing so we can better grasp the situation. This doesn't seem like a way to achieve power factor correction to me. If you assume that the neutral and ground are hard bonded at an entrance, having same on both ends of a transformer winding would seem to be asking for neutral/ground loop currents and a failed transformer down the road.
