Abstract

The DC current injected into the earth from the grounding electrodes of HVDC system could flow into the oil and gas pipelines through their grounding, lead to high pipe-to-soil potential. It is necessary to study the measures to solve the effect of DC current on metal pipelines. In this paper, the pipe-to-soil potential under field test is measured and calculated. Several measures on metal pipeline is discussed in a real case. It is found that the pipe segmental insulation and laying sacrificial anodes on pipe used jointly is effective to reduce the pipe-to-soil potential. Maintaining an effective safety distance of DC grounding electrode and metal pipeline is an important way to address the interaction.
