Determine the capacitive reactance in ohm miles for the line of Problem 5.3. Assume the conductor's outside diameter is 1,602 in. Repeat by including earth effects given that the ground clearance is 136 ft.
Problem 5.3
Repeat Problem 5.2 for a phase separation of 35 ft.
Problem 5.2
Calculate the inductive reactance in ohms/mile/phase for a 500-kV, single circuit, two-subconductor bundle line with ACSR 84/19 subconductor for which the GMR is 0.0534 ft. Assume horizontal phase configuration with 33.5-ft phase separation. Assume bundle separation is 18 in.
A three-phase induction motor is required to operate from a single-phase source. One possible connection is shown in Figure P18.28. Will the motor work? Explain why or why not.
A load consisting of a 480 ohms resistor in parallel with a (5/9) uF capacitor is connected across across the terminals of a sinusoidal voltage source Vg, where Vg=240cos5000t V. a) What is the peak value of the instantaneous power delivered by the..
Autocorrelation and Tao, question from my ECE 302 class regarding the mean of a random process given a particular autocorrelation function in terms of tao.
A proportional control system id to be used to control the wing flaps of a jet airplane. The wind load is expected to cause as much as 600 in*lb of torque. The system should be able to keep the flaps to within 5 degrees of the set point.
The output-port(drain-source terminals) of an n-channel depletetion -mode MOSFET with parameters K=0.25mA/V^2 and Vtr= - 2Vis connected to a Thevenin circuit consisting of Vdd=7V andRd=1.5kOhm.
Phase current - Neutral Grounded Assume that the load is star connected with the neutral grounded. Each phase has a series RL load with R = 5 ohms and L = 20 mH. Calculate and plot the Phase a current Ia using Fourier techniques.
Design a counter that counts pulses on line 'w' and displays the count in the sequence 0,1,3,2,0,1,3,2,0,1. Use D flip-flops in the circuit.
The ALU required for this lab accepts two 4-bit inputs (A0 - A3, B0 - B3), a 3-bit function selection code (F0 - F2) and outputs a 5-bit result (S0 - S4). Since the function selection uses 3-bits, there are 8 different functions.
Determine the power factor (lagging) of the motor. Find the value of the capacitance C that must be connected across the motor to raise the pf to unity.
