if a balanced, three-phase, 15MW total load is fed by a 138Kv power line at a 0.85 lagging power factor, determine the following. (a) The line current (b) The value of the capacitor in uf per phase, is a wye-connected capacitor bank is used to correct the power factor to a 0.95 lagging power factor.
And how long it will take to reach that temperature assuming no heat lost in the process and comments on your results and may research the properties of nichrom wire to determine the resistivity of the wire
A circular loop of radius a is located in the y-z plane center at the origin in the presence of a uniform B field pointed in the +x direction. At t=0 the loop is rotated counter clockwise with radial frequency about the z-axis.
What is the smallest number of samples that could be collected in order to know for sure whether or not the 1000Hz component is present? Assume you are using a Rectangular window.
To familiarize yourself with the Internet Standards, search the Internet for the IETF RFC website. Using the information you find on this site, answer the following questions: Identify four types of Internet standards.
A 150MW alternator generates an open-circut line-t0-line voltage of 12kV at nomial DC excitiation. When the terminals are placed in short-circuit the resulting current per phase is 8000A. a) Calculate the approximate value of the synchronous reacta..
A control system for positioning the head of a floppy disk drive has the closed-loop transfer function T(s)=11.1(s+18) / (s+20)(s^2+4s+10). Plot the poles and zeros of this system and discuss the dominance of the complex poles.
Ziegler-Nichols Open Loop Tuning Often, when working with a faster loop, many people will opt only for a PI control philosophy
To digitally manipulate information we must encode it using binary numbers. Consider an encoding for playing cards. There are 52 cards in a deck and they are divided
Plotting Continuous time signal, Consider the following continuous signal: x(t) = 10e^-3t u(t) Using Matlab, plot the continuous-time signal over the range -1=
Draw the logic diagram for the following Boolean expressions. The diagram should correspond exactly to the equation. Assume that the complements of the inputs are not available. a.) XYZ+X'Y'+X'Y'
A U manometer reads 20 cm air as operating fluid and a given manometric fluid. A single branch closed tube reads 35 cm connected to point 1. If P2 = 1.2 ATM calculate the pressure in point 1 and the density of the manometric fluid.
A temperature sensor has a static transfer function of 0.15 mV/C° and a time constant of 3.3 s. If a step change of 22° to 50° C is applied at t=0, find the output voltage at 0.5 s from t=0s to t=10s. What is the indicated temperature at these tim..
