Cahora Bassa was operational trhought the Mozambican civil war, I am a mzambican and I know that, the article says it was not operational. That was one of the key infrastructure the Goverment protectd heavilly including placing land mines around the poles197.249.228.160 (talk) 09:35, 8 April 2013 (UTC)Reply

The papers cited in the article say 2000 towers were damanged and that transmission stopped in 1985. A citation of a document stating the contrary would be required. --Wtshymanski (talk) 13:48, 8 April 2013 (UTC)Reply

the article reads

The HVDC-power line from Cabora-Bassa is a symmetric HVDC, which can transmit 1920 megawatts at a voltage level of 533 kilovolts and 1800 amperes.

Do the math, 533k*1800=~960M Or am I missing something? VdSV9•♫ 14:26, 10 May 2006 (UTC)Reply

Probably +/- 533 kV - double the line-to-line voltage but each pole only withstands 533 kV to earth. --Wtshymanski 02:13, 11 May 2006 (UTC)Reply

Good one, thanks. :) VdSV9•♫

Yes, that is the case. The system has two monopolar and (almost) independent lines; each of them can operate at +/-533KV at 1800A. Each line can carry up to 960MW. Usually they are operated at symmetric volatges in order to reduce the current and subsequent corrosion effects in the earth electrode; but at least in theory they can be both operated at positive or negative voltages (altough not at full power, since the earth electrode would not withstand the full 3600A that would arise in this case).

I looked around for some kind of Wikipedia style guide on doing this and couldn't quickly find one, so I just followed the style that seems to be common in wire service (AP, Reuters, etc) articles.
