3 phase (was LF: G3KEV)

["Dr. Wolf Ostwald" <df2py@t-online.de>]

hi John !
all understood. I guess in Germany we had a unique situation, as after 
WW2 a lot of infrastructure was destroyed and when it came to new 
installations, in urban and industrial areas 3 phase was chosen. Guess 
in the Fifties most of the "farmers`s lines"  were taken out and 3 phase 
came in.
Even cars and motorbikes have 3 phase alternators now. If material is of 
concern and energy transfer not too demanding, then single phase can do 
it. Look at the US, in a lot of areas, not only the remote ones, you 
find "farmer`s lines" even in the middle of a city. Low voltages have to 
be paid for by conductor size and heating of connections. The later 
posing an everlasting threat to home appliance security.
