A cathodic protection unit (12) utilizes a signal generated by a conducting wire (14) inserted into a clamp body (16) after the clamp (16) is attached to a pipe (P). The wire (14) wraps a complete number of turns around the clamp structure. When the clamp is attached to the exterior of the pipe (P), the conducting wire (14) makes contact with the pipe (P) via a slight clamping pressure. Analyzing two signals generated by separate conducting wires (14) are used for cathodic protection.

Corrosion protection of steel in concrete is provided by locating an anode assembly including both a sacrificial anode and an impressed current anode in contact with the concrete and providing an impressed current from a power supply to the anode. The impressed current anode forms a perforated sleeve surrounding a rod of the sacrificial anode material with an activated ionically-conductive filler material between. The system can be used without the power supply in sacrificial mode or when the power supply is connected, the impressed current anode can be powered to provide an impressed current system and/or to recharge the sacrificial anode from sacrificial anode corrosion products.
