SOLID STATE DECOUPLER

 

GENERAL

 

 


The Solid-State Decoupler (SSD) is designed to provide DC decoupling and AC continuity/ grounding simultaneously when used with cathodically protected structures.

 

The SSD is now a popular choice amongst other technologies such as polarization cell, metal oxide varistors, and gapped arrestors with ratings for AC fault current and lightning, and the abitlity to pass steady-state AC current.

 

TYPICAL APPLICATION

 

-          Decoupling gradient control mats from pipeline

-          Over voltage protection of equipment

-          AC mitigation

-          Decoupling of disimiliar metals that must be AC bonded for safety
