We have a balanced y-y system where the total power delivered to the Load is 1188 KW. wITH A lAGGING pOWER fACTOR OF 0.6. tHE LINE VOLTAGE AT THE LOAD IS 6600v. The line Impedance is 0.5+0.4j ohms.
a) Find the power lost in the line.
b) To reduce the line loss we want to reduce the Magnitude of I by 36.755%. To accomplish this we use a bank of Delta connected Caps across the Load. Let frequency=60hz. Find the value of the Caps.
A 500-kVA, 60Hz, 5000V, Y-connected, 10 pole synchronous has internal parameters of Armature Resistance 1ohm amd Synchronous Reactance 10ohms. The generator is operating at rated values and 0.9 pf leading.
If the speed of the crate at A is 15 ft/s which is increasing at a rate v=3 ft/s^2, determine the magnitude of the acceleration of the crate at this instant. [crate is on an incline sliding back toward the orgin at a distance of 10ft
A 10 kVA 1100:120 V single phase transformer has the following circuit parameters referred to the primary. Rc = 80 k Ohm, Xm = 10 k Ohm, Re = 20 Ohm, Xe = 50 Ohm. If the secondary load impedance is 5
Two point charges q1 = 2.0 C and q2 = 1.0 are fixed in a plane at the positions given by the Cartesian coordinates shown in the figure at right. Consider that they are in a vacuum, where ko = 9.0 × 109 N.m2/C2.
Research the recent history of gasoline pricing in your area, and attempt to relate any fluctuations you observe to documented supply and demand factors outlined in our book. Be sure to cite any references used.
As speed increases, the lower lamp, L1 lights, then L1 and L2, then, L1, L2, and L3, until all lamps light at the highest speed. Once all the lamps illuminate, no further increase in speed will have any effect on the display.
A three-phase, wye-connected induction motor is supplied by a three-phase and foursin system with line-to-line voltage of 220V and the impedance of the motor is 6.3+j3.05Ohm per phase.
Drift velocity the actual (physical) velocity of electrons along the wire. Transmission velocity the rate at which information can be transmitted electronically using conducing wires. How is it possible that the transmission velocity is so much faste..
Efficiency of MOSFET circuit provide in datasheets of any product is measured at transient state of my output node or staedy state?
The average orbital radius of Neptune is 2.8 billion miles. Given that distance, how long on average does it take light from the sun to reach the planet Neptune in hours (Speed of light in English system = 186,282.4 miles/second)
You deposit 10% of your annual salary at the each of each year in a retirement account. F= Future worth A1= first annual deposit n=number of years g=geometric gradient F=A1(1-(1+g)^n(1+i)^-n/(i-g))(1+i)^n use Matlab to graph the function.
The 9s complement of a BCD digit can be used similarly to the way ones and twos complements of binary numbers are used preform subtraction via addition. The 9s complement of a BCD digit is simply the BCD coded result of subtracting the digit from ..
