AC Mitigation Services

JST provides AC Mitigation system modelling & design, construction, operation and maintenance.

With the ever growing need to maximize land resources and reduce land acquisition costs it is now common for transmission and distribution pipelines to be installed and operated in common corridors or rights of way with High Voltage AC (HHVAC) Electrical Power Transmission Tower Networks.
Nace International


Pipelines that are buried (or aboveground) and run with or cross HHVAC power lines in shared rights of way are subject to electromagnetically and fault induced AC currents.  These unwanted but unavoidable  AC currents present a risk of electric shock hazard to the general public or pipeline personnel and can give rise to destructive AC corrosion on affected pipelines.

Fortunately – the harmful effects of these AC currents can be controlled and mitigated against, ensuring safe and long service pipeline operation through the considered use of AC Mitigation Computerized Modelling and the design, application and maintenance of engineered AC Mitigation measures.
