AC Mitigation is making material selections to add forms of grounding to the pipeline system. Without a decoupler installed between the grounding and the pipeline, these systems would reduce the effectiveness of the cathodic protection system due to the additional bare surface area being added to the protected structure. There are three (3) primary reasons why a pipeline operating company would need AC Mitigation:
They operate a pipeline that is co-located in a high voltage transmission right of way;
- …..and experience high induced AC voltage on their system causing 15 volts AC or greater. This has a potential to shock any personnel that come into contact with the structure
- …..and need to lower AC current density in order to reduce corrosion threat.
- Prevent voltage spikes during fault conditions of the AC transmission system
JRGO offers a turnkey construction solution for the installation of all Induced AC & Stray Current DC interference designs and components.
