Spin Up Tests - Pos & Neg. Seq. Vectors

[soma]

These are problems 4-02 and 5-02. I think the answers for these are switched. Any thoughts?

Also, problem 1-64, there is no zero sequence network in line-line fault but the solution for this problem shows zero seq. network, which is incorrect.

I would appreciate any inputs here. Thanks

Look at the rotation from the point of view on the x-axis. They look correct.

Soma I agree I don't understand how to view these phasors.

Samelec, thanks for your input.

Lielec, I was reading positive seq. as negative and neg as positive seq. but I got them now. Do you have same issue ? If not let me know what is it you are having difficulty with.

Thanks,

I just think I'm confused on how to look at it from the point of view of the x axis. Following the circles I don't understand
