  • SYSTEM FOR MITIGATING INDUCED ALTERNATING CURRENT (AC) ON PIPELINES
    Publication number: 20170220057
    Abstract: An alternating current (AC) mitigation system reduces undesired AC current induced in a pipe section by the electromagnet field of a nearby electrical utility power line. An active feedback system processes samples of the undesired AC signal from a current sensor located at the pipe section. A feedback controller generates a current compensation signal that is applied to the pipe section at a current coupler to cancel out the undesired AC signal. Corrosion of the pipe section caused by the undesired AC current may be reduced or eliminated.
