Perhaps some of you may be interested in these pictures of pole mounted transformers.
We're always interested in stuff like that around here!
Welcome to the forum Martin.
Wolfgang,
That means that you have 1 phase distribution on the Isles?
Yes, to a limited degree. As soon as you get anywhere with a concentration of houses in a village or town you'll find 3-phase transformers with a 4-wire 240/415V distribution network around the settlement (each house tapped for 240V single-phase service).
In more rural areas though, you'll often see single-phase spur lines tapped from the 3-ph 11kV network running for relatively short distance to serve isolated houses. The two single-phase xfmrs in my post above are such examples, each one serving just a couple of houses which stand on their own in the countryside.
This being a mostly rural area, we also have little hamlets which have maybe a dozen or two homes spread out along a lane over a distance of maybe a half mile in what is otherwise a fairly isolated area. Some of these have a single-phase (2-wire) 11kV spur line and a single-phase xfmr which feeds 3-wire 240/480V distribution lines which run through the settlement, again with the houses just tapped for 240V 2-wire service.
Here's an example of the latter (notice the three LV wires and two fuses):
The single-phase HV spur in this example continues a short distance to a xfmr serving another tiny isolated community.
