Automated cathodic protection monitor and control system

摘要

An automated, remote control/monitoring system for a cathodic protection system for a buried metallic object based on monitoring multiple coupon test stations, buried next to the metal object, by a central processor, which can individually control multiple cathodic protection rectifiers. Preferably, the reference for potential measurements is a buried coupon having a metallurgy substantially the same as the metallurgy of the buried object.
