Abstract:
A method for inhibiting corrosion of a component of a marine vessel when an electrical system of the marine vessel is connected in electrical communication with an electrical conductor, comprising the step of:providing a first circuit point which is connectable in electrical communication with said component; providing a second circuit point which is connectable in electrical communication with said electrical conductor; monitoring a voltage potential of a third point which is representative of said voltage potential proximate said first point; and causing an electronic current to flow in a direction from said second point to said first point, said electric current being controlled according to a first process when said voltage potential of said third point is above a preselected threshold magnitude, said electric current being controlled according to a second process when said voltage potential of said third point is below said preselected threshold magnitude, said first process comprising the step of selecting an imposed magnitude of said electronic current as a function of said voltage potential of said third point in order to achieve a predetermined target magnitude of said voltage potential of said third point, said second process comprising the step of selecting an imposed magnitude of electric current independently of said voltage potential of said third point.
