04050 Telluric Currents and Their Effect on Cathodic Protection of Pipelines

Product Number: 51300-04050-SG

ISBN: 04050 2004 CP

Telluric currents cause variations in pipe-to-soil potentials that take the potentials outside the desired range for cathodic protection. This paper reviews the causes of telluric currents, such as geomagnetic storms and tidal water movements, and shows how knowledge of these phenomena can be used to determine the occurrence of telluric current in pipelines.

HISTORICAL DOCUMENT. This NACE International standard practice establishes the general principles to be adopted to minimize the effects of stray current corrosion caused by direct current (DC) and/or alternating current (AC) from external sources on steel reinforced concrete (RC) and prestressed concrete (PC) structures or structural elements. The standard practice offers guidance for the design of concrete structures that may be subject to stray-current corrosion; the detection of stray current interference; the selection of protection measures; and the selection of mitigation methods.
