Mike,

Not true about the power line voltage. There are a good number of 500
and 765 KV AC transmission lines and +/-500 KV DC transmission lines in
the US and they are experimenting with UHV AC lines up to 2.25 MV!
"Voltage levels of AC transmission circuits vary from 34,500 to
2,250,000 volts" quote from page 4-10 in The Lineman's and Cableman's
Handbook/ eighth edition
