Scottish government's latest announcement.

Star sounds like wye in the US.

The US over head service uses 4160 3 phase line to line, then each house the transformer is tapped line to neutral for 2080ish volts. Then those transformers supply two lines of center tapped neural power. Line to line is 240v either line to neutral is 120v. All 60hz.

I'm moving into a house with a deep high volume well. That well uses a 3 phase motor. I don't want to pay to have that 3 phase hooked back up. If the motor is still good I am going to run it off variable frequency.

Star and Wye are the same. I know the nominal voltage in the US is 120, but we were always told to calculate for 110 in an industrial situation. The 60 Hz coils never lasted long on 50 Hz.
In the UK we have sub stations in a local, supplied by HV on underground cables. It is then stepped down to 3 phase and the houses are supplied with single phase on a balanced network street by street.

I was photographing an LPG tanker waiting to go into Braefoot Bay, to pick up Ethylene from the Exxon Mobil terminal here in Fife, and on working on the image I noticed the plethora of wind turbines along the skyline. These are just above the city of Edinburgh, Scotland's capital.


I also photographed this shale oil carrier from Wilmingham, waiting to go up river to the refineries at Grangemouth. We are importing a lot of US shale oils as the Scottish government does not allow fracking here in Scotland, not even test boring, as they do in England.


The rig in the back ground is on care and maintenance, in the shelter of the Firth of Forth.
