ABSTRACT:
In a system for cathodically protecting an underground metallic structure where a sacrificial anode material encasing a metal core is in electrical communication with the structure, the core can be automatically and galvanically disconnected from electrical communication with the structure after the anode material has been consumed, by inserting in series between the structure and the core a corrodible link made of a material which is less galvanically active than the anode material but more galvanically active than the material of the core. At least a portion of the corrodible link is exposed to the underground environment, so that upon consumption of the anode material, the corrodible link will corrode and break the connection between the core and the underground structure.
