DC Stray Current Interference:<\/strong> D.C. systems may cause currents to flow in the earth or any other electrolyte, whether intentional or unintentional. A few examples of these systems include: d.c. traction systems, HVDC systems, PV power systems, geomagnetic interference, etc. When for personnel safety, earthing or equipotential bonding is necessary, special care shall be taken in order to avoid stray currents that may be leading to accelerated corrosion of supporting and third-party metallic infrastructure. Stray current corrosion refers to corrosion damage to metallic infrastructure resulting from DC flow other than in the intended circuit.<\/p>\t\t\t\t\t\t\t<\/div>\r\n\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div><\/div>\r\n\t\t<\/section>\r\n\t\t\t\t
