Title: Shipwrecks - Impressed Current
Post by: frog1944 on October 02, 2017, 08:17:31 am
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
