Back Up Protection Schema

05/01/2011 12:39 PM

Hi list: In my opinion : Best option like back up protection schema is deploy 67, 67N relays; don´t care a multy feeded smart grid?.

I´d be very interested to read your opinions.

All the best to everyone.

Jair.

The OP wasn't understandable enough to provoke even an underly religous/political comment.

The 67N may be even more difficult to set and test than it was as a single function in an old electromechanical relay.

And, I meant what I said about the "D".
