From schulz at ece.msstate.edu Mon Apr 7 13:11:01 2008 From: schulz at ece.msstate.edu (Noel N Schulz) Date: Mon Apr 7 13:11:11 2008 Subject: [ece4633] Monday's homework Message-ID: <22164036.65951207591861310.JavaMail.root@zimbra.ece.msstate.edu> All - I have had a couple questions for Monday's homework. First assume that it is a bolted fault for problems 9.11 and 9.29. Also for modified Problem 9.29 it should say "Also, for the single line-to-ground fault at bus 2, determine the curents and voltages at the terminals of generators G1 and G2".

They asked me to move our test. I cannot do it any night but Wednesday. So I am proposing that we take it on Friday, April 18 in class. It will only be on Chapter 9 and Sections (7.3, 7.4 -- balanced 3 phase faults). I will make it short since it will only be 50 minutes. Please let me know if you have a problem with this.

Both solutions will be okay.
