This presentation describes the influence of local soils, geology, and even shallow ground water in AC power induction on well-coated steel pipelines. It evaluates medium-voltage AC (MVAC) power lines causing pipeline interactions, in addition to the high-voltage AC (HVAC) power lines usually suspected. It discusses influence from complicated MVAC (and possibly pipeline) geometries. Finally, it describes the use of AC power distribution capacitors used for power conditioning, and a highly unusual interaction identified, between a well-coated steel pipeline and a faulty capacitor.

Comparing AC Study Techniques In Addressing AC Corrosion Risk

AC interference studies have become increasingly popular in an industry where shared right of ways have increased and there has been a better understanding of how AC interacts between pipelines and powerlines that are collocated with each other. While modeling software for AC interference studies have been developed since the 1990s, advancement in AC interference processes have occurred as more has been learned over the years. When performing an AC interference study there are three steps that need to be completed: field data collection, modeling, and mitigation design. Within this paper, we can compare a project from ten years ago to a project from today to understand the developments that have been made over the course of time to improve the way we develop our mitigation designs.

Several alternating current (AC) coupon test stations (CTS) located near AC power lines were investigated to assess the AC interference corrosion risk of the test coupons. Asstation consisted of two ½ inch (1.27 cm) diameter and 1received each AC test inch (2.54 cm) long carbon steel (CS ) coupons. Coupons are much larger than 1 cm 2 and current density measurements are not 100% relatable to the SP21424 or ISO 18086 criteria, since these refer to measurements on (typically) 1 cm2 . The current densities measured on the coupons in this study will underestimate the AC corrosion threat.
