The Polarization Cell Replacement (PCR) is a solid-state device designed to simultaneously provide DC decoupling and AC continuity/grounding when used with cathodically protected structures, such as pipelines, tanks, grounding systems, and cable casings.  Commonly used to decouple electric equipment from grounding systems, for AC Mitigation projects, or other isolation and grounding applications, the PCR provides safety grounding while also isolating your cathodically protected structure, improving CP system performance. With a higher blocking voltage than polarization cells and other technologies, the PCR eliminates the need for placing devices in series. Additionally, high AC fault current and lightning surge current ratings provide long-life with a low risk of product failure making it an ideal solution. The PCR has been used by customers around the world and is the original solid-state decoupler offered to the industry.
