I'm trying to finish and need within 5 hours
Ok thanks, XXXXX XXXXX graduate level Power Systems Transients course problems and the use of laplace transforms is requested as needed by the prof, as much detail as possible would be helpful. Thanks
It is not stated in the problem so assume 60Hz
I just noticed it requested information from question 3.2 so i'm uploading the question for reference.
I have reviewed the problem and it is verbatim from the book.
Ok, thank you, XXXXX XXXXX is much appreciated.
thank you, I have another 3 questions i've posted under engineering, if you are interrested in looking at them for me. they are simpler than the other 2
* it keeps erroring out when i try to post a new question. Is it possible to increase pay for this problem?
3.3Figure 3P.2 shows two capacitor banks, C1 and C2, in a substation. C1 is energized, but C2 is discharged. The three-phase, 60 Hz rating of the banks are: C1, 5 MVA; C2, 3 MVA, on a 13.8 kV base. The source has a short circuit rating of 20kA rms at 13.8 kV. The inductance of the loop between C1 and C2, represented by L2 is 30μH.
Attachments are only available to registered users.Register Here Calculate the peak transient voltage that will appear on C2 and the peak transient current that will flow in L1, if the switch S is closed at the peak of the voltage cycle. Point out any assumptions you make.3.5

A line to ground fault occurs as indicated in Fig. 3P.4, close to the secondary terminals of a 230/34.5 kV transformer. The transformer has a three-phase rating of 100 MVA; it has 0.1 pu reactance on this base.Calculate:a.The fault currentb.The time to peak of the transient recovery voltage when the circuit breaker opens to interrupt the fault current. A value of 12.7nF can be assumed for the effective capacitance per phase of the transformer secondary winding. 3.12
C1=100μF; C2=40μF; L1=10mH; L2=20mH; C1 and L1 in Fig. 3P.8. are oscillating; C2 and L2 are de-energized. The switch is closed when V(C1 )=0 and I2=500A. Calculate: a.Peak voltage reached on C2b.Peak current reached in L2c.Frequency of the current in L1d.Maximum voltage on C1 prior to closing the switch
Soon, today preferably, I'm a web student and going to submit my assignment late but i'd rather late than never. I'm hoping by getting help i'll be able to drill down the funamentals of the problems more accurately.
I was finally able to resubmit the homework question if you would like to pick it up from there.
