Here is a link to some stuff that will can help you get your head around faults and sequence components.

I would also recommend -
Power Systems Analysis by Grainger and Stevenson.
Symmetrical Components for Power System Engineering - by Blackburn - this was meant to be a companion to his relaying book
Circuit Analyses of A-C Systems vol. 1 and 2 by Edith Clarke - both of these volumes are very well written. She does a very good job at explaining and giving insight into her analyses. This is out of print and it is hard to find original copies but it is out of copyright and you can get a pdf through most universities if you have access or can purchase a copy of from India as a print on demand hardcover for $15-20 a vol.

RE: impedance sequence
If you intend to follow IEC way-IEC 60909-0 for instance-you have IEC 60909-2 SECTION 2: DATA FOR ELECTRICAL EQUIPMENT. You could find here data on typical synchronous, induction machines, transformers, overhead line and cables.
