Thinkgood:

i dont know what to say but that is very odd but i did heard some kind of protection by injecting small DC not AC current with very low votage too.

myself i did see one on major petroleum pipeline it have small power device to inject the dc power to prevent corrosion on pipe line.

i know this is kinda of odd item to see it but if anyone else know about this please do pitch in here.

merci, marc
