A/C Mitigation Strategies Light Up Corrosion Seminar

摘要

In the U.S. and many other countries, shared land use by pipelines and other utilities is common. This trend means the number of overhead high-voltage transmission lines parallel to and sharing a common corridor with underground pipelines has increased, and they all need grounding to prevent interference by alternating current (A/C). At its fourth annual integrity seminar, Mears Group, Inc., part of Quanta Services, focused on the topic of A/C mitigation. A combination of classroom presentations and a field demo at Mears' state-of-the-art field test facility in Rosebush, MI attracted more than 75 pipeline integrity personnel. Kevin Garrity, Vice President of Integrity Solutions for Mears Group, Inc., began by discussing pipeline integrity problems in shared power line rights-of-way.
