AC Interference Mitigation and Grounding
BSS Technologies delivers AC mitigation and grounding solutions for asset & personnel protection. We use advanced modelling, testing, and active decoupling to block hazardous induced voltages.
Why AC Mitigation Matters?
Pipelines and steel assets located near high-voltage power lines can be exposed to induced alternating currents. If left unmanaged, these currents can accelerate corrosion, create safety hazards, and compromise the integrity of pipeline systems. We combine precise predictive modelling with physical testing and hardware installations to discharge unwanted currents, protect isolating joints, and maintain worker safety.

How, When & Where
Understand the fundamentals of AC Mitigation: How it’s performed, when it’s necessary and where it’s applied.
How is AC Mitigation Achieved?
AC mitigation is achieved by engineering and installing specialized grounding equipment that safely redirects hazardous induced electrical currents away from buried pipelines. This process relies on active devices like Solid State Decouplers (SSDs) and passive zinc ribbon systems that drain AC faults to the earth while maintaining critical DC cathodic protection isolation. The final system is precisely designed using advanced computer modelling and field resistivity testing to ensure total pipeline integrity and absolute worker safety.
When is AC Mitigation Necessary?
AC mitigation is absolutely necessary whenever buried steel pipelines are routed parallel to high-voltage transmission lines, electrified transit railways, or shared utility corridors. The electromagnetic fields in these areas continuously induce dangerous alternating currents onto the metal assets. Mitigation must be implemented when predictive models or field tests show induced voltages exceeding safe industry thresholds, preventing rapid AC corrosion and lethal shock hazards.
Where is AC Mitigation Applied?
These mitigation systems are applied across extensive onshore pipeline networks, oil and gas processing facilities, and crowded utility right-of-ways exposed to heavy electrical interference. The technology is specifically targeted at exposed above-ground appurtenances where personnel touch hazards are highest. This includes block valve stations, pig launchers and receivers, metering skids, and test stations, ensuring the entire infrastructure remains protected from power surges.
Benefits of Implementing AC Mitigation
Improve Personnel & Public Safety: Eliminate hazardous touch and step voltage risks on exposed structural valves and test stations.
Reduce AC-Induced Corrosion: Prevent rapid metal loss and localized pitting on buried steel caused by continuous stray AC currents.
Protect Critical Pipeline Assets: Stop high-voltage arcing across isolating flanges and minimize coating puncture during system faults.
Maintain Regulatory Compliance: Ensure your mitigation systems strictly meet international and client standards.
Extend Infrastructure Service Life: Maximize the operational longevity and overall reliability of critical networks near power lines.
