Abstract: A test station assembly for monitoring a cathodic protection system of a buried or submerged structure includes a housing including an inner chamber a connector, and an opening. In addition, the test station assembly includes a pole to connect to the connector such that an electrical conductor extending through the pole and connected to a coupon assembly is configured enter into the inner chamber. Further, the test station assembly includes a face plate to attach to the housing to at least partially cover the opening and an electrically conductive test post to connect to the face plate. Still further, the test station assembly includes a cap to cover the test post outside of the inner chamber. The cap includes an internal passage to receive the test post therein, and an opening into the internal passage to receive a probe of a voltmeter therethrough to contact the test post.

Abstract: Assemblies and methods for maintaining cathodic monitoring of underground structures may include an electrode watering assembly having a cap that includes a cap body of a rigid material defining one or more chambers adjacent to a proximal electrode end of a permanent reference electrode when installed thereon. The cap body may include a distal cap end defining a distal opening configured to be disposed around the proximal electrode end and a proximal cap end defining a proximal opening. The electrode watering assembly may include a conduit having a flexible material. The conduit may include a distal conduit end configured to be fluidly coupled to the proximal opening and a proximal conduit end configured to be positioned at a cathodic test station, such that fluid directed into the proximal conduit end is directed through the conduit and into the one or more chambers for watering at least the proximal electrode end.

Abstract: Assemblies and methods for monitoring the cathodic protection of underground or submerged structures may include a coupon assembly including a conductive test coupon and a reference electrode for determining the voltage potential difference of the protected structure without substantially interrupting surrounding current sources. The reference electrode may be at least partially covered with an electrolytic material in electrical contact with the surrounding environment via a plug including a porous material. A method of installation of the assembly may allow a single technician to install the coupon assembly using a probe rod without extensive on-site excavation. The coupon assembly may be configured to seat securely with the probe rod for stability during installation, and release from the probe rob when the probe rod is separated from the coupon assembly and withdrawn from the ground, leaving the coupon assembly at a preselected depth or preselected distance from the protected structure.

Abstract: An embodiment of an electrode watering assembly includes a cap having a cap body with a reservoir adjacent to a proximal electrode end of a permanent reference electrode when installed thereon. The cap body may include (i) a distal cap end defining a distal opening configured to be disposed around the proximal electrode end, (ii) a proximal cap end defining a proximal opening, and (iii) an outer wall defining an overflow port therethrough to receive overflow fluid from the reservoir and direct the overflow fluid out of the reservoir. The electrode watering assembly may include a conduit having a distal conduit end configured to be fluidly coupled to the proximal opening and a proximal conduit end configured to be positioned at a cathodic test station. Thus, fluid directed into the proximal conduit end is directed through the conduit and into the reservoir for watering at least the proximal electrode end.
