SA>I was searching for information on electricity distribution systems
SA>in South Australia & was quite surprised at the number of high
SA>voltage direct current transmission lines either installed or being
SA>installed around the world.

SA>Some examples I found are Lake Erie Link, Harbor Cable (New Jersey
SA>to New York), Direct Link (NSW - Queensland) & Murray Link - 200
SA>MVA HVDC "light transmission system" (NSW to South Aust). From what
SA>I've seen of Murray Link on the news, it looks little more than 2"
SA>diameter, direct buried in a trench.

SA>My understanding was that DC had lost out to AC a century ago (Thomas
SA>Edison) for power distribution due to resistance losses & inefficiencies.

SA>Does anyone know of any compelling reasons for adopting DC for high
SA>voltage transmission?

Thanks to Edison and Tesla, absolutely no. (And we New Englanders would
lose the great power AC we buy from our Canadians neighbors 8-(

Ciao, Ack.
