Here are a few boosters going into the test (from classes).
A load draws a fundamental frequency current of 100 amps and a 3rd harmonic current of unknown magnitude. The load is drawn via a transformer with a K factor of 2.6. There are no other harmonic oders present. What is the maximum 3rd harmonic current?
Ans: I have I(3rd)=Square root (2500) = 50 Amps
An automobile has a top speed of 120 miles per hour. When that car travels a 100 miles per hour, what is its per-unit speed?
Ans:.833 pu
Good luck on Friday guys. Art / Wolverine, I think it?s been a thoughtful process having some practice problems discussions held. Thanks.
