I haven't posted here in a while, but hello! I am now under taking my masters and have run into a conundrum. We are working on transmission line modeling, and I have the following homework problem: 2) The per-phase impedance of a short three-phase transmission line is 0.5∠53.15◦ Ω. The...

I posted this in another thread, but thought i would share in a new thread so everyone could see. A lot of universities have free open courses online. MIT has a boat load of them, in all manner of subjects, including power systems. Check out this site. I downloaded and am using some of the...

See I thought I had these down... Could someone with a moment help me clarify these two problems? Are there differences? I found the right answer on 525, but when I applied the same thought process to 535, i found the wrong answer. They appear, to me at least to be similar. Any help would be...

Sorry for the two in a row But i was thinking about this one as well. Why will the current be higher with the additional of the cap? Shouldn't this LOWER the total current required by the motor, since now the apparent power needed is supplied at the motor rather then over the conductors and...

Forgive me if this is answered somewhere else, I wish that I could search by "129" in this site.... BUT for this problem, the NCEES answer uses the effective Z from Table 9...which is for a pf of .85...but the pf for this problem is at .8...so shouldn't Z be calculated from the values given in...
