AC Mitigation Field Data Collection

To determine the need for AC Mitigation and design effective AC mitigation systems, it is necessary to gather the following data:

Typical Electrical Transmission Data

• Tower geometry
• Tower grounding / earthing details
• Phase conductor arrangement
• Phase arrangement
• Conductor heights
• Conductor separation distances
• Shield wire data
• Locations of any phase transpositions
• Current loading under different conditions namely:
  • Average conditions
  • Maximum conditions
• Emergency conditions (for power line with multiple circuits)
• Fault information i.e. Duration, magnitude, etc.
• Power line-to-ground fault currents

Pipeline Data

• Physical attributes of the pipeline
• Detailed pipe depth of cover and centerline location in areas of collocation with the overhead AC lines
• Coating type and conductance
• Pipeline diameter
• Presence of valves, traps, casings, pig launchers, etc.

Soil Data

• Accurate soil resistivity data at various layers along the collocation

Qualified MATCOR AC Mitigation technicians can visit your site to collect all necessary data to evaluate fault current and induced AC corrosion risks, and identify safety risks in accordance with the latest NACE and industry standards. Data gathered is utilized for sophisticated pipeline AC modeling [LINK: pipeline-ac-modeling]that supports effective design.
