Polarization Cell Replacement

The 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.

The PCR has very high AC fault current and lightning surge current ratings. With a higher blocking voltage than polarization cells, the PCR eliminates the need for placing devices in series, making it the most ideal isolation and grounding product for cathodically protected structures. In addition to out-performing polarization cells, the PCR also surpasses metal oxide varistors and gapped arresters, clamping lightning-caused over-voltages to the lowest possible levels.
