Overview
AC interference occurs when transmission or distribution facilities are located near metallic infrastructure such as pipelines, railways, communication systems, or other metallic assets.
Electromagnetic coupling under normal or fault conditions may result in hazardous induced voltages and currents, creating safety concerns for personnel, impacting pipeline integrity and cathodic protection systems, and affecting nearby infrastructure.
Utilities, pipeline/railway operators, and governing standards often require AC Interference Studies to assess potential impacts and determine appropriate mitigation measures.
