The ALCOA conductor tables from Glover, Sarma, Power System Analysis and Design, are here. Similar tables are available from all manufacturers of conductors.1. A 60 Hz, 765 kV three-phase overhead transmission line has four ACSR 1113 kcmil 54/3 conductors per phase. Determine the 60 Hz resistance of this line in ohms per km per phase at 50o C. (0.0151 ohms/km per phase)
2. A 7 kV 60 Hz single phase two-wire overhead line has 1/0 copper conductors with 1 m horizontally between conductors. Calculate R (0.607 ohms/mile) and L (2.274 uH/m).
3. A 12 kV 60 Hz three-phase three-wire overhead line has Drake ACSR conductors spaced 4 ft apart in an equilateral triangle. Calculate R (0.1288 ohms/mile) and L (0.9339 uH/m)
4. A 230 kV, 60 Hz, three-phase transposed overhead transmission line has one ACSR 954 kcmil conductor per phase and flat horizontal spacing with 8 m between adjacent conductors. Determine the inductance in H/m and the inductive reactance in ohms/km (1.3 uH/m, 0.506 ohms/km).
A silver-coated sphere of radius 5 cm carries a total charge of 12 nC uniformly distributedon its surface in free space. (a)Calculate |D| on the surface of the sphere and (b)external to the sphere
Two input capture events occur at counts 0x1037 (first event) and 0xFF20 (second event) of the free-running counter. How many counts, in decimal, have transpired between these two events
Why developing software for wireless devices is challenging? List and briefly describe the two (2) reasons given in your textbook for why developing software for wireless devices is challenging.
explain the dilation, erosion, closing, and opening operations on a binary image B with a structured element S. ( you need to use the symbolic notion for the operators, but need not provide the precise mathematical definitions
Discuss the sequence of actions that occur in the operation of an automatic washing machine. Indicate which actions are time-driven and which actions are event-driven.
A digital communication system transmits one of the three values -1,0,1. A channel adds noise to cause the decoder to sometimes make an error. The error rates are 12.5% if a -1 is transmitted, 75% if a 0 is transmitted, and 12.5% if a 1 is transmi..
