P2746 - IEEE Draft Guide for Evaluating AC Interference on Linear Facilities Co-Located Near Transmission Lines
Project Details
This guide identifies the mechanisms and analysis approach fo 1 r ac interference effects 2 on conductive linear facilities due to the operation of co-located electric transmission lines. The 3 common mechanisms for ac interference including magnetic inductive coupling, capacitive 4 coupling, and conductive voltage transfer through soil are discussed. Included are general 5 guidelines and considerations for performing detailed ac interference analyses, with sections 6 specific to the analysis of co-located pipeline and railroad facilities. This guide does not dictate 7 specific compliance limits, direct when an ac interference analysis must be performed, or cover 8 other issues that may need to be considered in joint-use corridors, such as effects due to 9 lightning striking the line or dc corrosion on structures.
