Galvanic anodes rely on the galvanic series potentials of the metals to drive cathodic protection current from the anode to the structure being protected.

"Having an accurate cathodic protection measurement is extremely important to knowing that you have the proper amount of current on that wire, " he said.
43.
The relative reactivity of zinc and its ability to attract oxidation to itself makes it an efficient sacrificial anode in cathodic protection ( CP ).

David Kilian, a Koch safety director, said in a sworn statement that the company had authorized repairs to the cathodic protection system but encountered delays.
45.
In July 2011, Navy Public Information Officer Christopher G . Johnson said that a " cathodic protection system " would be installed on the ship.
46.
Deaver said that if the current flowing through the cathodic protection wire is too low, the wire will fail to protect the pipeline from corrosion.
47.
The company was also the first in the industry to develop a gas-fired generator to produce electricity for cathodic protection to fight corrosion on pipelines.
48.
Pipeline companies are required to periodically measure electrical conditions in the surrounding soil to make sure this " cathodic protection " system is working properly.
49.
Some cathodic protection transformer-rectifier units are designed with taps on the transformer windings and jumper terminals to select the voltage output of the ICCP system.
50.
The most aggressive contributor to corrosion of underground plant is dc stray current from electrified rail transportation systems, cathodic protection rectifiers, or welding and mining operations.
