The nameplate on a 7.97-kV: 460-V, 75-kVA, single-phase transformer indicates that it has a series reactance of 12 percent (0.12 per unit).
a. Calculate the series reactance in ohms as referred to (i) the low-voltage terminal and (ii) the high-voltage terminal.
b. If three of these transformers are connected in a three-phase Y-Y connection, calculate (i) the three-phase voltage and power rating, (ii) the per unit impedance of the transformer bank, (iii) the series reactance in ohms as referred to the high-voltage terminal, and (iv) the series reactance in ohms as referred to the low-voltage terminal.
c. Repeat part (b) if the three transformers are connected in Y on their HV side and A on their low-voltage side.
The parameters of an n-channel enhancement-mode MOSFER are VTN = 0.5V, k'n = 120μA/v2, and W/L = 4. What is the maximum value of λ and the minimum value of VA such that for VGs = 2V, ro ≥ 200kΩ?
Given the following function in product-of-sums form, not necessarily minimized, F(W,X,Y,Z) = (W + X' + Y')(W' + Z')(W + Y), Re-express the function in the canonical sum-of-products form. Use little m notation.
Please explanation how a Parallel RLC Filter circuit behave at Low Frequencies, Resonant Frequency and High Frequencies
Convert the following to hexadecimal 1600 sub script 10 2. compute the sum of the following pairs of signed 6-bits binary numbers. In parallel, show the operands and the answer in decimal. Indicate if or if not an overflow occurs.
design an embedded system that will include four ultrasonic range finders - assume these have 10m range one 3-axis
Suppose two points P1 and P2 are tossed at random and independently onto a line segment of length L. What is the probability that the absolute distance between the two points does not exceed l.
Two statistically dependent random variables x1 and x2 are applied at the inputs to a threshold detector , the output from which is equal to the number of inputs that exceed the threshold T. Thus, y = 0, 1 or 2.
AWG 14 solid copper house wire is designed to operate within a temperture range of -40 degree C to +90 degree C. calculate the resistence of 200 circuit feet of wire at both temperatures.
The binary-coded-decimal (BCD) format uses 4 bits to represent 10 decimal digits. For example, 259 in base 10 is repesented as "010 0101 101" in BCD format. A BCD incrementor adds 1 to a number in BCD format.
Describe the features of your organization that indicate which kind of organization it is. Describe five steps your organization could take to become better and move up in the scale. Do you think it is likely that this kind of change could happen ..
A 150-KW, 300 V shunt generator has Ra= 0.1ohms and Rf=60ohms, If the generator operates at the rated voltage, calculate the induced voltage at (a) full-load (b) half-full load (which means the load current is half)
Design a circuit with output f and inputs x0,x1,y0 and y1. Let X = x0x1 be a number, where the four possible values of X, namely 00,01,10,11, represents the four numbers 0,1,2,3 respectively. The same thing with Y = y0y1.
