Copper grounding has a detrimental effect on cathodic protection (CP) of interconnected underground carbon steel piping. The copper can consume large amounts of protection current as well as introducing significant measurement errors when verifying the protection level of the piping. This paper examines the interaction […]

Monitoring the operation of Cathodic Protection (CP) systems on 39,000km (22,000 miles) of pipeline through site visits and manual reading is a time consuming and costly task. (Figure 1) Of the 1300 plus rectifies sites in the subject pipeline network, more than 40 sites are […]
