Abstract
Field readings of induced AC voltage and AC current density from test points along a pipeline are regarded as an indicator of corrosion risk and personnel hazard caused by AC interference from collocated powerlines. Field data also provides the foundation to develop predictive modeling for AC mitigation design. A major technical challenge during modeling often results from unavailable current loads of collocated powerlines. This report introduces our experience regarding this situation and provides a solution option. It is demonstrated that current loads can be estimated via simulating the field reading profiles. The model based on the estimated current loads is applicable in AC mitigation design.
