Common name for the cathodic protection technician: the person who drives the right-of-way reading rectifiers and test stations, runs annual and close interval surveys, installs anodes and bonds, and hunts down shorts and interference. The job mixes field electrical work, electrochemistry and regulatory record keeping, and is commonly certified at tester, technician and specialist levels.
