Mitigation with Cathodic Protection
Cathodic protection can sometimes be used to overcome stray current
problems. This will work if the stray current is not so large that it cannot be
overcome with the cathodic protection current. An advantage of using
cathodic protection is that it avoids the use of bonds and the installation and
maintenance problems that may accompany them.
Galvanic anodes may be used to overcome cathodic interference problems.
Anodes are placed in the area of current discharge. The testing and design
of such systems are, however, beyond the scope of this course.
