AC for simple long-distance transmission...
Except for underwater cables, where it can cause unacceptable
transmission losses.

How does immersing a 11kV AC cable in water increase transmission
losses? This isn't a joke question, I can't see how the medium
surrounding a cable changes the action of the cable itself, other
than cooling effects.

jgh

Inductive and Capactive losses theres some stuff on the AAB website
somewhere;!...

Not sure that induction plays any part..


Wouldn't have thought it would be but the article alluded to was very
comprehensive as to the reasons why it was a problem...

Seek ye here!...
