File talk:4263517 High voltage direct current system.png

The title is reasonably precise and identifies the patent number that the figure was used to illustrate. The patent text appears not to reserve any special copyright for this figure adn identifies it as "prior art" - the figure was used only to illustrate the parts of an HVDC system and does not in itself depict any of the claims in the patent. --Wtshymanski (talk) 14:30, 13 August 2009 (UTC)
