Doubt if it is DC. Most transmission lines in NA are AC as far as I
know, especially since the Canada-US systems are intertwined and share
power on linked grids.
This is the scheme where a helicopter borne worker first hooks on then
transfers himself to the live transmission wire in order to work on
the connections, separators, insulators etc.?
Thre is some talk of transmitting electrical power from the proposed
Lower Churchill generating site in Newfoundland, Labrador across to
the island portion of that province, then some 80 miles across the
Gulf of St. Lawrence to Nova Scotia, New Brunswick and New York
State.
Due to the long underwater link would think DC would be used there;
with converters at each end.
By the way. In that vein (DC underwater cables); anybody know the
answer to this question .....?
"There was or is a DC power cable across the north of the North Sea
beween Scotland and Norway????" Purpose of which to share power
between those two countries which have hydro generating capabilities.
Seem to remember reading about it in the mid 1950s.
