Annotation:
The article presents an improved methodology for identifying a geomagnetically-induced current source affecting the main pipeline and the operation of electrochemical protection devices. The methodology contains the scope and procedure for work and measurements, the implementation of which allows identifying the stray current source and, if the source is geomagnetic, provide for measures to minimize its negative impact and increase the effectiveness of anti-corrosion protection of underground sections of gas and oil pipelines.
