Solid State decoupler
It is used for protecting the preventing the flow of CP current up to a predetermined voltage threshold,while passing any induced AC current.
Applications:
1 Decoupling gradient control mats (grouding mats) from pipelines
2 Over-voltage protection of equipment from AC faults,lightning,and switching transients
3 Decoupling dissimilar metals that must otherwise be AC bonded for safety
4 AC grouding and DC isolation of electrical equipment integral to a cathodically protected system
5 Mitigation of induced AC voltage
6 Blocking voltage or threshold voltage
7 DC leakage current for a given blocking voltage
8 AC fault current rating
9 Lightning surge current rating
10 Steady-state AC current rating
