Spark Gaps vs. DC Decouplers for Over-Voltage Use hosted by Materials Performance

  • This event has passed.

Both isolating spark gaps and DC decouplers are commonly used to protect against over-voltage conditions on pipeline isolation joints and storage tanks where cathodic protection systems are applied. Though spark gap devices are often applied because of their relatively low cost, they are not designed for many over-voltage conditions that commonly occur on pipelines. Without fully understanding the limitations of spark gap devices, pipeline operators may unwittingly put their pipeline assets as well as operating personnel at risk from over-voltage events such as AC faults and lightning.

In this webcast, attendees will learn: 

  • An overview of over-voltage protection of isolation joints;
  • A high-level understanding of spark gap and DC decoupler technologies;
  • A detailed, data-driven analysis of spark gap performance in over-voltage conditions;
  • An analysis of performance benefits in solid-state devices.
