Abstract
A pipeline AC mitigation SSD Marker Station has a shape and land surface area footprint that are similar to conventional pipeline location markers or corrosion test stations. The SSD Marker Station includes an SSD device that connects an underground metallic pipeline to an underground grounding conductor. The SSD Marker Station further includes a disconnect switch configured to disconnect the SSD device from the pipeline and/or grounding conductor. Also included is a pair of testing ports that are in electrical communication with the SSD device. Testing of the SSD device thereby requires only operating the disconnect switch to isolate the SSD device from the pipeline and/or grounding connector and performing an electrical measurement across the testing ports. In embodiments, the SSD Marker Station meets all requirements applicable to a pipeline location marker, and can be installed in lieu of a pipeline location marker.
