Title: Fundamentals of cathodic protection interference

Abstract

The primary cause of cathodic interference was initially related to operation of direct current (DC) traction systems, such as rail systems, mining carts, and the like. Nowadays the increased use of impressed current cathodic protection (ICCP) systems for pipelines and other underground and submerged metallic structures has become another major cause of cathodic interference. With the requirements of cathodic protection (CP) installations on some underground storage tanks (USTs) and the renewed interest by municipalities installing DC traction light rail systems, a higher level of cathodic interference can be expected. Although interference may be caused by stray earth currents from many different sources, this discussion only concerns interference caused by earth currents produced by the operation of ICCP systems. All forms of interference correction require considerable field work and testing by knowledgeable and experienced personnel. It can be time consuming and therefore very expensive. Much of this expense can be saved if careful planning is done in the design stage before a CP installation is made.
