Is the grounded conductor in a 2-wire 230/240 volt system fed to each home
referred to as "neutral" even in UK?
One common neutral that is grounded back at the nearest transformer
substation, and three phases, fed singly to homes in a reasonably 'balanced'
way (loading-wise). So one side of the street may be fed from one phase, and
the other side of the street from a different phase, then further up the
street, some more houses connected to the remaining phase and so on. Each
house also has a protective ground connection. Generally, no 'pole pigs'
except in rural areas. For the most part, each collection of several hundred
houses, are connected underground to a small building containing 3 phase
transformers. I think that the input to these stations is around 11kV, also
underground. The 'hot' side of the supply is usually known as "live" in the
UK, but is sometimes also known as "phase".
I'm not an electrical engineer, but that's pretty much the basis of the UK
domestic distribution system. Commercial premises usually have a full three
phase plus neutral connection to the network.
