Passed power in Kentucky. Third time was a charm for me. This Forum helped to keep me motivated. Thanks a lot.

In a 3-phase rectifier circuit, the silicon controlled rectifiers have firing angles of 0 degrees. If the incoming voltage waveform is v(t) = 460 sin(wt) where w= 377, what is the average voltage across the load. The solution doesnt show the graph I would expect for the answer and the answer is...

Question For a 3-phase fault at location a, calculate the 12kv short circuit current is Tline = j.0145/1000ft T1 - 3-Phase, 60/12-kV, 7.5MVA Xfmr, with 7.5% impedance (inductive) 60kV ] ]________ T1 ______Tline _____ X____ to resistive load ] ] Simple fault question Can't figure out...

I am in Lexington, KY and taking the Power Electrical PE exam in October 2010. I am opened to a study group. Anyone interested? Thank you
