Monitoring hardware

Cathodic Protection Test Stations

A cathodic protection test station provides controlled, accessible measurement and connection points for structure, reference electrode, coupon, anode, bond and monitoring circuits.

The station is built from two coordinated documents: a general arrangement that defines the enclosure and installation, and a terminal schedule or schematic that defines every electrical function inside it.

Components, labels and continuity are checked before release.

Product overview

The technical definition comes before the catalogue name.

A controlled product page separates the component's function, product construction and acceptance data from the wider cathodic protection design. This prevents a familiar name from hiding missing material, interface or inspection requirements.

Primary function
Provide repeatable field access for potential, current, continuity, bond and coupon measurements.
Typical circuits
Pipe, casing, reference electrode, coupon, galvanic anode, bond, shunt, spare and monitoring channels.
Critical interfaces
Terminal identification, cable glands, link/shunt ratings, enclosure protection, mounting and project tags.
Configuration control
No terminal is treated as generic; every position maps to a field cable and schematic function.

Product construction

What the finished product contains

A professional test station makes the field circuit understandable at first inspection. Physical access, terminal spacing and labeling are designed around actual cable sizes and measurement tasks.

01

Post or enclosure

Powder-coated steel, stainless steel, GRP, PVC or project-selected construction with mounting, access and finish defined on the GA.

02

Terminal board

Insulating support with terminal spacing, touch clearance and usable tool access matched to conductor and hardware size.

03

Terminals and links

Color-coded or tagged terminals, removable links, shunts, resistors or surge components arranged to the schematic.

04

Cable entry system

Glands, conduits, grommets, sealing and strain relief coordinated with cable quantity and outside diameter.

05

Identification

External station tag, internal terminal designations, warning labels and durable circuit schedule.

06

Monitoring provision

Reserved space, DIN rail, antenna/power interfaces or mounting plate only when defined by the monitoring design.

Applicable standards

Standards mapped to the part they actually control

Listing a standard is not a certification claim. The purchase specification must identify the required edition, clauses, tests and evidence. Project documents take precedence where they add or modify requirements.

Standard and roleScopeHow it applies to this product
ISO 15589-1:2026CP system standard Cathodic protection of on-land pipeline transportation systems, covering design, materials, equipment, installation and inspection. The system designer's requirements for anodes, monitoring points, cabling, equipment and commissioning. It is not a standalone manufacturing certificate for every component.
NACE SP0169-2024Corrosion-control practice Control of external corrosion on underground or submerged metallic piping systems. CP criteria, design and installation context. Product configuration still follows the purchase specification and approved drawings.
NACE TM0497-2022Measurement method Field measurement techniques related to CP criteria on underground or submerged metallic piping. Measurement arrangement, reference-electrode use and cautionary measures. It does not define a universal reference-electrode product construction.
IEC 60529:1989+A1:1999+A2:2013Enclosure classification IP Code classification for protection provided by electrical enclosures. A required IP rating must be stated and supported by the selected enclosure or agreed assembly verification; it cannot be inferred from appearance.
IEC 62262:2002+A1:2021Mechanical-impact classification IK Code classification for protection of electrical enclosures against external mechanical impacts. Apply only when an IK rating is specified and supported by the enclosure design or evidence included in the order scope.
IEC 61666:2010+A1:2021Terminal identification General principles for identification of terminals within industrial systems and equipment. Terminal designations and schedules where the project adopts this identification approach.

Edition review completed 22 July 2026. The edition named in the project requisition or purchase order remains the contractual basis.

Manufacturing control

From approved data to an inspectable product

The process is organized around released drawings, material identity, controlled interfaces and inspection records. No unapproved change is treated as equivalent by default.

01

Drawing release

Approve the GA, terminal schedule, schematic, BOM, gland schedule, labels and inspection plan as one document set.

02

Enclosure fabrication

Form/fabricate the post or enclosure, prepare access features and apply the specified finish or select the approved enclosure.

03

Panel preparation

Lay out the terminal board and component mounting so cable bend radius, tool access and clear identification are maintained.

04

Component assembly

Install terminals, links, shunts, glands and internal conductors exactly to the released BOM and schematic.

05

Identification

Apply station tag, internal terminal labels, polarity and circuit schedule after checking against the drawing revision.

06

Factory verification

Perform dimensional, component, continuity, link/shunt and functional checks defined in the FAT/ITP.

07

Protected packing

Secure access panels, loose accessories and keys, and protect the finish and glands for transport and site storage.

Inspection and test plan

Checks tied to a stated acceptance basis

Inspection is useful only when the method, acceptance document and product identity are recorded together.

Application range

Where this product family is used

  • Cross-country pipelines
  • Water transmission systems
  • Tank farms
  • Plant piping
  • Insulating-joint monitoring
  • Coupon and reference points
  • Bond/interference locations

Engineering selection notes

Points that should remain visible in technical review

  • Do not select enclosure size before the terminal count, component layout, cable OD and bend space are known.
  • An IP or NEMA label is not assumed from a stainless or painted enclosure; evidence scope must be defined.
  • Hazardous-area equipment requires explicit classification, certified components and a project-approved design; it is not implied by a standard test station.

Technical questions

Common specification points

Answers focus on product definition and evidence, not on sales instructions.

What is the minimum drawing set for a custom test station?

A general arrangement, terminal schedule or wiring schematic, BOM/component ratings, cable/gland schedule, marking schedule and inspection requirements should be controlled together.

How is the terminal layout verified?

Each terminal is checked against the schedule for identity, component type, connection and continuity. Links, shunts and polarity-sensitive devices receive additional value or orientation checks.

Does a metal enclosure automatically have an IP rating?

No. IEC 60529 classifies tested enclosure protection. The required rating and supporting enclosure/assembly evidence must be stated in the project scope.

What makes a station monitoring-ready?

The exact device, dimensions, power, antenna, communication, cable and environmental interfaces must be defined. Empty space alone is not a complete monitoring-ready design.
