SSMC 10kA/50A-2/1–LP-S Solid State Mitigation Cell
SSMC is a robust polarization cell designed to divert induced AC current to the ground. The internal impedance of the Cell is so large for DC current up to a preset DC voltage and almost short circuit for AC current which makes it possible to bypass the AC current to ground while not affecting the Cathodic protection current of the structure.
The Cell switches on for any voltage present on the protected Structure which is 2.0 V negative or 1.0V positive with respect to ground and switches off if the voltage of the pipeline is between these limits, providing overvoltage protection for the pipeline up to the fault current ratings.
The Cell does not require any maintenance, can be used in any mounting position and under any whether conditions because of its sealed structure.
