How to test a polarization cell?

Solid State Mitigation Cells (SSMC, PCR, Polarization cell) are indispensable parts in terms of many functions such as static, AC current discharge of cathodically protected structures, safety grounding, and equipotential generation etc.

Checking whether these cells fulfill their functions before and after installation ensures that the system can be set up properly and the installed system can be operated correctly.

Why a separate cathode connection is needed for reference electrode?

A connection of separate measurement cable to the cathode connection point may be needed for the reference electrode. This is due to the erroneous voltage of measurements done over the current carrying cathode cable. Moreover, if the cathode cable breaks…
