A polarization cell replacement (PCR) is a solid-state device designed to concurrently provide DC decoupling and AC continuity/grounding when used with cathodically protected structures, such as: Pipelines, Tanks, Grounding systems, Cable casings. The solid-state design eliminates the maintenance requirements and the potentially hazardous electrolytes associated with polarization cells, making the PCR are an ideal replacement for electrochemical polarization cells. Common PCR applications include: Insulated joint protection, AC voltage mitigation, Decoupling electric equipment grounding systems & Decoupling from utility grounding systems.
