This paper discusses case studies of high voltage direct current (HVDC) & high voltage alternating
current (HVAC) crossing Pipelines right of way (RoW) showcasing the effects of alternating current
(AC) interference with respect to AC corrosion and Safety Hazards while running parallel and crossing
at different angles to the same pipeline at multiple locations in a short span of length and restricting the
AC current & safe voltage within maximum tolerable limits through deployment of mitigation measures
as per industry code of practice, globally.
The paper discusses effects of both powerline fault conditions as well as induced steady state on
underground pipelines, AC interference modelling for enhancing effectiveness of Cathodic protection
and analysis of AC interference mitigation measures. A comprehensive technical analysis involving
collection of baseline information on both the pipeline and powerline and determining powerline fault
current effects adjacent to each tower, on the pipe wall, the pipe coating, and the resulting safety
hazard for pipeline personnel.
