A three-phase generator supplies two three-phase loads. The 2.4 kV generator is rated at 180 kVA. The per-unit impedance of Load 1 is ZLoad1=80%+j75% and for Load 2 is ZLoad2=70%+j25% on 200 kVA and 2.5 kV bases.
(a) Draw the equivalent circuit.
(b) Determine the ohmic value of the impedances.
(c) Calculate the source current in amperes and in percent if the generator operating voltage is 3.8 kV (line-to-line) and a reactance of X=125% is connected in series with the generator voltage.
A 10kO potentiometer sensor is used to measure displacement and is connected to a voltage source of 5V. The full range of the displacement is 10mm. When the potentiometer is at 4mm of its maximum displacement.
In this problem you will design a Moore finite state machine that realizes a synchronous 3-bit counter with a mode control input M and three outputs QA, QB, and Qc. When M = 0, the counter output advances through the 3-bit numbers using a step si..
Determine the capacitive reactance to neutral in ohm-meters and the capacitive reactance of the line in ohms if its length is 125 mi.
Design a circuit to hold the lightsfor the indicated time. To help in the solution draw a blockdiagram of the problem, then a circuit diagram, then the requiredcalculations and values for all the circuit elements and finally the results to support..
A composite analog signal is given in the following expression: x(t)=1.2 sin(2pi60ft)+0.0001cos(2pi1ft) -If this signal was sampled at 1000 Hz, derive the expression for the sampled sequence x[n] with n being the sampling index.
A load operating at 6400 Vrms draws 56 A at a PF of0.812 lagging. Find: (a) the peak current in amperes (b) the instantaneous power at t=2.5 ms assuming an operating frequency of 60 Hz
Discuss why it is important to consider the Gain Bandwith Product (GBW) and the Slew Rate (SR) when selecting an op amp for a particular application. What other factors are important and why.
Two machines and a lighting load are connected in parallel to a 220 V, 60 Hz line. The first machine uses 40 kW of power at 0.81 power factor lagging. The second machine uses 27 kVA at 0.93 power factor leading.
A bidirectional shift register is one in which the datacan be shifted either left or right. It can be implemented by usinggate logic that enables the transfer of a data bit from one stageto the next stage to the right or to the left, depending on ..
Determine the respective lengths l1 and l2 of the two inner and outer pieces of timber that will yield the same factor of safety as the original design.
Genetic algorithms represent an optimization approach where a search is made to "evolve" a solution algorithm, which will retain the "most ?t" components in a procedure that is analogous to biological evolution through
