FT Switches for Dual Protection Scheme
FT Switches for Dual Protection Scheme
(OP)
Gentlemen,
Could anybody please upload a correct three line diagram showing how four FT switches (two for each relay) are used with one CT in a dual protective relay scheme (Make A & B) for a simple 50/51 function?
Thanks in advance

This link looks questionable, but Google ABB Test Switches and download their engineering data. There are typical wiring diagrams in the catalog.

Thanks for your input. I downloaded the contents but it gives only the three line for a single relay and not for a dual relay scheme.
