Medium-voltage cable inductive coupling to metallic pipelines: A comprehensive study

In this work a comprehensive study of the electromagnetic interference problem on a metallic pipeline exposed to medium voltage underground cable systems is presented. Simulations are carried out using the well-known software package ATP-EMTP and results of the induced voltages on the metallic pipeline are presented for several operating conditions and configurations. Results show that the induced voltages significantly depend on the cable configuration, whereas high and hazardous voltage levels may be arise as the asymmetry in the cable flowing currents increases with the worst case being the single-phase to ground fault.
