A 3-phase, 600 kVA synchronous generator has a rated line voltage of 3300 V. The stator winding is star connected and has a resistance of 0.37 0/phase. Its synchronous impedance is 4.3 0/phase. a) Draw the synchronous generator's per phase voltage and current phasor diagram. b) Calculate the per phase output voltage. c) Determine the voltage dropped across the synchronous impedance. d) Calculate the synchronous generators voltage regulation and output power for full loads having power factors of: Unity and lagging.
A coil with resistance 3Ω and inductance 100 mH is connectedin series with a capacitor of 50 pF, a resistor of 6Ω, and asignal generator that gives 110 V rms at all frequencies. Calculate ωo ,Q, and B at resonance of the resultant series RLC circu..
A 2000 microfarad capacitor, initially charged to 100 volts, is discharged by a steady current of 100 microamps. How long does it take to discharge the capacitor to 0 volts
Consider the half wave rectifier with a 100Ω load and a peak voltage of 3.5 V. For a 1000μF capacitor, calculate the ripple amplitude if the frequency is 60 Hz.
design a resonance circuit with following specifications: L = 10 mH, RL = 4W, Imax = 200 mA, fs = 10kHz, Q = 20. That is, determine the required R, C, and supply Voltage E. For R and C, use the closest standard values.
Write an equation relating the donor-atom concentration, the acceptor-atom concentration, the free-electron concentration, and the hole concentration for a doped semiconductor.
a load of 300 kw is driven by a 3-phase motor of 0.9 efficiency. the motor has a power factor of 0.7 lagging and is
A. There are three part conveyor lines (1-2-3) feeding a main conveyor. Each of the three conveyor lines has its own counter. Construct a PLC program to obtain the total count of parts on the main conveyor. B. Add a timer to the program that will ..
Although sums behave like integrals, because of the discrete nature of the sums one needs to be careful with the upper and lower limits more than in the integral. To illustrate this, consider the separation of an integral into two integrals.
The boom AC is supported at A by a ball and socket joint and by two cables BDC and CE. Cable BDC is continuous and passes over a pulley at D. Calculate the tension in the cables and the x,y,z components of the reaction at A if the crate has a weig..
The power supplied by a certain battery is a constant 6.0 W over the first 5 minutes, zero for the next 2 min, a value that increases linearly from zero to 10 W during the next 10 minutes, and a power that decreases linearly from 10W to zero in th..
Build a 5-Bit Adder with the following specifications: Must include the Carry Look Ahead Technique. Must be able to add the 2's complement of B to A, when a subtraction is made.
