Pipelines and Overhead Power Cable
Pipelines and Overhead Power Cable
(OP)
Hi,
what is the minimum allowable separation distance between a pipeline and overhead powerlines?
I know that power cables can affect the cathodic protection of the pipelines and that is just about it really.
Has anyone heard of a typical drawing for a pipeline/ overhead powercable situation as well?
Thanks everyone

RE: Pipelines and Overhead Power Cable
Induced voltages in pipelines and communications cables shall not
exceed twelve (12) volts under normal (i.e., steady-state) conditions.
Under fault conditions, induced voltages shall not exceed the values
calculated from formulas in IEEE STD 80.
Overhead powerlines that are 69 kV and below do not create a touch
potential hazard when placed according to the allowable limits.
