ECN Forum Forums Photo Discussion Forums Photos for General Discussion Primaries of pole mounted transformers

Here is an American open delta setup with a 3-wire (no MGN) primary. Grounding is done by local rod at the pole. This particular setup is in the high desert area in Sothern California Edison territory where I noticed that most, if not all of the local distribution, was done with no MGN and the transformers connected L-L. This would be considered unusual by US standards which is mostly MGN distribution.
