## Irritating Engineering Question

There should be a catagory for stuff like this xD

I'm studying for a resit on Saturday next week about electrical power and I was working ot these tutorials I had. Now I have these fault current questions which I think I am working out correctly, but my answer is always coming out incorrect. I'm not sure if the answers given are correct anyway, because the lecturer screwed up many times.

I've searched many times on the internet about how to work them out, all giving me the same method, and still my answer is wrong.

Can someone have a look at this and possibly tell me how to work it out? I'm supposed to use the pu method. (ie. reduce to a fault impedance at the point of the fault, and take its reciprocal since E(pu) = 1.0pu)

Um, maybe you should try realgeek.com

Its the weekend and I can't be expected to think - plus, EE was like 15 years ago for me!

OMG!

I did something like this in 8th grade lol but not this complex

Don't look at me. I failed a Post Office job test many years ago because I thought a 'microfarad' was a small Arab.....

In the illustration I see a butterfly holding a dildo, is that what I'm supposed to see? What does it mean?

The answer is correct. Start out on the end of the circuit and calculate back. I made ther assumption that all current flowing through C was defaulted to ground.

Oh, one thing you may be missing. Look at the transformers. This is obviously three phase.

Lmao, I think you are looking at the wrong picture. But, hey, if you have the dildo you can hold my butterfly anytime. LoL.

Golly, now that I look at it for a bit, G1 kinda' looks like Gonad 1, and G2 kinda' looks like Gonad 2.

Dude, I'm barely beginning my Engineering degree. I wish I could help. At least now I know who to go to when I take circuit analysis!!

Hehe, thanks for the help twomack, and the funny jokes guys. I'll try it out again, hopefully I'll manage somehow. :s If only the lecturer showed us how to work it out. Grr.
