Strengthening pipeline corrosion protection to enable long-term infrastructure operation
For cathodic protection technicians, a voltage reading is only useful when the reference point behind that reading is dependable. During pipeline surveys, troubleshooting, commissioning, and routine cathodic protection inspections, technicians often focus on the digital voltmeter, test lead, or measurement procedure. However, the Portable Copper/Copper Sulfate Reference Electrode (Cu/CuSO₄ Reference Electrode or CSE) is equally important because it provides the reference potential against which the structure-to-electrolyte potential is measured. Portable Cu/CuSO₄ reference electrodes are widely associated with field cathodic protection measurements on buried metallic structures, including manual pipe-to-soil readings and survey work such as CIS and DCVG.

Solid-State Decoupler (SSD) for Cathodic Protection and AC Mitigation
A Solid-State Decoupler (SSD) is a passive electrical protection device designed for cathodically protected pipelines, tanks, grounding systems, isolation joints and other metallic structures where DC isolation must be maintained while AC current, fault current and lightning surge energy require a controlled path to ground. For pipelines operating near high-voltage transmission lines, substations, electrified railway systems or other sources of electromagnetic interference, induced AC voltage can create personnel safety risks, increase AC corrosion exposure and interfere with cathodic protection performance. The JUDUN Solid-State Decoupler provides a practical method of combining cathodic protection isolation, continuous AC grounding and transient overvoltage protection in a single passive device.
