| Abstract: | Stray current can cause great damage to buried steel pipelines,and seriously threatens the safe application.The smart stray current mapper(SCM)is used to detect stray current on buried steel pipeline,with the results showing that the SCM has a variety of functions,so it can detect the magnitude and orientation of all kinds of stray current,eliminate the needless interferential signal,and determine the type and source of stray current.The SCM can estimate the inflow and discharge points exactly and provide a... |
