This cabling you're talking about....Are you saying that there are 3 wires
out on the main pole BEFORE the step-down tranformer, or after?
I've seen variations in Fort Wayne, most are 2 wire delivery (or
transmission) lines around the city, I've seen 3 or 4 wire 3 phase systems
in the industrial areas, and I've seen any where from 2 wire up to 4 wire in
residential areas, but these 4 wire systems are actually 2 two wire
delivery lines supplying a larger residential area.
Wanna know what I think is weird? How about the delivery line into my
neighborhood.....for the life of me, I can't figure out how ONE WIRE
supplies our transformers.....that 2nd wire is well hid, or they're actually
using the land as a return ground path at the transformer.
Man, go figure.
