Polarization cell

Polarization Cell

DC decouplers such as a capacitor, polarization cells, or polarization cell replacements (PCR) connected between pipe and a separate “earthing” structure will reduce the cathodic protection requirements when a more noble ground is tied directly to the structure. A DC decoupler allows AC current to pass but blocks DC current.

They are available for using on buried oil, gas, and water pipelines which share the same right-of-way as high voltage power lines.

PETUNIA supplied two types of polarization cells:

• Liquid Polarization Cell

• Solid Polarization Cell or Polarization Cell Replacement (PCR)
