I have been fascinated by the discussion of HV DC lines and would be
grateful if the following questions could be answered.
I beg the indulgence of the moderator for this off-topic topic.
1 How is the HV DC contrived. Generated HV or rectified?
2 Once it reaches the other end, how it is turned back into AC?
Motor-generators, really big inverters?
3 What are typical voltage ranges and distances travel led?
4 Do the lines rely on the earth for "return" or do they run + and - ?
