A 10 MVA, 6.9 KV. star connected generator has positive, negative and zero sequence reactance of 25, 20 and 7% respectively. An inductive reactor with 6% reactance based on the rating of the generator is placed in the line from neutral to ground. For a line to line fault at the generator terminals when it is operating atrated voltage and is disconnected from the system determine, (a) Initial symmetrical r.m.s. line and neutral currents and (b) line to line and line to neutral voltages.
1. Write an algorithm to carry out subtraction of two binary numbers (the skeleton was given in the class). Include all the conditions for the given numbers. 2. Write an algorithm to carry out multiplication of two binary numbers using r..
Determine a suitable sampling frequency. Design a notch filter to remove the 50Hz component, paying particular attention to any assumptions you have made in the design.
Otherwise determine where any other states will go. Draw a transition tablebased on the state diagram. Design a combinational logic diagram using only NAND gates in addition to the flip flopsand BCD to seven segment display.
Box 1 contains 5 red, 6 white, and 9 blue balls. Box 2 contains 7 red, 8 white, and 4 blue balls. A ball is withdrawn at random from Box 1 and placed in Box 2. Then, a ball is taken at random from Box 2.
A small gasoline engine can put out 18,000 N-m/min of mechanical power. The engine is used to drive an electrical generator that is 80 percent efficient. 1 N-m = 2.78 X 10-4 W-h. Find the output of the generator in Watts.
write a program that calculates the quadratic equation. the program should be able to compute imaginary numbers (i.e. sqrt(-1)). finally, output the tow result. hint: the computer cannot directly compute imaginary numbers
Suppose that a current x(t) = e^-0.5t for t > or equal to 0, and zero otherwise is applied to a discharged capacitor of capacitance C =1F at t = 0 sec. What would be the voltage in the capacitor at t= 1 seconds
Air enters an adiabatic nozzle at 3 atm pressure and 100oF and emerges at 1 atm and 30oF. The inlet velocity is negligible. What is the discharge velocity
Your program should prompt the user to input the radius and height. The program should output the result with three digits after the decimal point. The output should include some explanatory text.
The steady state solution of stable systems is due to simple poles in the jO axis of the s-plane coming from the input. Suppose the transfer function of the system is: H_ (s)= (Y(s))/(X(s)) = 1/([(s+1)^2]+4))
The voltage across a resistor is given by Ohm's Law: V=R I. Write a program that asks for resistance R in ohms, and current I in amps for several resistors, then calculates and displays the voltage across each resistor.
A pulsar lies 1000 light years from Earth. The average plasma concentration is 1 el/cc. Using the plasma dispersion relationship for group speed, what is the group delay between a pulsar pulse received at 1 GHz and at 800 MHz
