Line Relaying--what should we know?

[tankfarms]

Hello, NCEES #521 threw me off a little bit, but when I read the answer, I felt that this is another case that they try to conceptually test your knowledge (simple huh?). Well, I just want to know, what are the expectations on the line relaying problems? (directional, distance, etc.) cause I know they can get real complex.

Thanks

Do not worry too much. Stay with the basis, for example, the length of the line included in each zone of protection...just to say something.
