A synchronous generator is rated 1,300 MVA, 22,000 volt, three phase, 3600 rpm, 60 Hz with a synchronous reactance of 0.35 ohms per phase. The machine is delivering rated output at rated voltage and 0.94 power factor lagging.
a) Find real power output of the generator
b) Find reactive power
c) Find line current (output)
d) Find voltage behind synchronous reactance - per phase - assume wye
e) Find angle delta and draw the phasor diagram
f) If the generator efficiency is 95 percent, how many hp must the prime mover supply?
The transfer function of a circuit is given by H(s)=2 s+4/4s^2+2s+2 a. Express the transfer function in a form in which the coefficients of the highest power of s are unity in both numerator and denominator. b. What is the characteristic equation o..
In a game, half of the (large) pool of potential opponents are beginners, a third intermediates, and one sixth are masters. Your chances of beating them are 60% for beginners, 30% for intermediates, and 10% for masters.
Inflation in years 1-5 equals 3.1 percent, 2.2 percent, 1.6 percent, 1.3 percent, and 1.1 percent, respectively.
Analysing harmonic content of ac voltage waveforms, An a.c. voltage, V, comprises of a fundamental voltage of 100 V rms at a frequency of 120 Hz, a 3rd harmonic which is 20% of the fundamental
A second method of development will recover only 50% of the ore deposit , but it will cost only $15 per ton of material removed.Subsequent processing of the removed ore recovers 300 pounds of metal from each ton of processed ore and cost $40 per ..
A DSSS-CDMA signal has a chip sequence that is 10,000 chips in length. The sequence repeats every millisecond. What is the chip rate?
Begin with a breadboard, wire, an RGB LED and some resistors. Using the forward voltages given in the RGB LED datasheet, calculate the correct current-limiting resistors needed to light each color of the LED (assuming VDD = +5V).
In a two-winding transformer N1 = 2000 and N2 = 500 and the supply voltage V1 = 1200 V. The transformer has winding resistances R1 = 2.0ohm and R2 = 0.125ohm , and leakage reactances X1 = 8.0 and X2 = 0.5ohm
Two Random variables have a joint probability distribution function defined by F(x,y)=0 X 1y>1 A). Sketch this distribution function. B). Find the joint probability density function and sketch it.
Each single phase transformer has an identical number of turns in the primary and secondary windings. If a line-to-line voltage of 480V is applied on the wye windings, compute the line-to-line voltage on the delta windings.
Write a recursive function that given integer n, counts down from n to 1. When the count reaches 0,your function should also display "GO!" Write a recursive function that takes a character array and prints the array without the vowels.
A circuit consists of two 1.0 k ohm resistors in series and this series being connected in parallel to a 570 ohm resistor. If the voltage drop across one of the 1.0 k ohm resistors is 4.5 V, what is the voltage drop across the 570 ohm resistor
