Shipwrecks - Impressed Current

Hi,

For the impressed current technique of protecting a steel structure, I read that they use a small DC voltage power supply? Why not  a large voltage one?
Also, for the inert electrode, is scrap pig iron sufficient (I’m aware that plated platinum titanium is sufficient)?

Thanks
