Corrosion and Corrosion Control
an endless battle against nature
Introduction DC stray current is defined as current flowing through the path other than the intended. The DC stray current could be either natural sources, e.g. telluric, metallic mineral deposit, or artificial sources, e.g. foreign pipeline, HVDC transmission line, DC…
