Induced Voltage on Gas Pipeline With Angle Between a Transmission Line

Abstract

This work presents the study of the influence of the electrostatic and magnetostatic fields from a power transmission line over a gas pipeline distribution system, for a non-parallel configuration. This approach is based on the nodal model analysis for power line, quantifying the capacitive and self and mutual impedance effects, due to the geometrical configuration of both systems, as they depend on the power line voltage and on the current in conductors, respectively. The non-parallelism is treated by piecewise approximation, discretizing these effects in a longitudinal and transversal way. An application was realized for a non-grounded gas pipeline configuration and with a mitigation wires protection system over the gas pipeline.
