P7.1. Solutions for line voltage and current for an open-circuited line. For a line open- circuited at the far end, as shown in Fig. 7.41, obtain the solutions for the phasor line voltage and current, and sketch the voltage and current standing-wave pat- terns, as in Fig. 7.4.

Each phase of a transmission line is a bundle of 4 conductors that form a square with all sides equal to d=33 cm. Each conductor is stranded and has GMR = 0.5 cm. Find GMR of the bundle to be used in inductance calculations. Express your answer in cm with 2 digits after decimal point

1- A single phase line has two parallel conductors 3m apart. The radius of each conductor is 1.2 cm. calculate the loop inductance per km of the line. 2- A single phase line has two parallel conductors 4m apart. The radius of each conductor is 2m. Calculate the capacitance per km of the line.

Q2: A single-phase transmission line consisting of two conductors, the radius of each conductor is 0.4 cm, the distance between the conductors is three and half meters and the height above ground is eight meter. The capacitance in µF/km without effect -1 of ground is إجابتك The capacitance in µF/km with effect of -2 ground is

Fill in the table for a correctly wired duplex outlet (U.S. National Electric Code standards for voltage PARAMETER EQUATION and frequency). Note the used of double- subscript notation. You can assume a 0° phase reference for Vba(t). Vba(t) Vea(t) Vbe(t) Vba (Peak Phasor) Vea (Peak Phasor) Vbc (Peak Phasor) Vba (RMS Phasor) Vea (RMS Phasor) Vbc (RMS Phasor) A C

Example 8.11. Each line of a 3-phase system is suspended by a string of 3 indentical insulators of self-capacitance C farad. The shunt capacitance of connecting metal work of each insulator is 0.2 C to earth and 0-1 C to line. Calculate the string efficiency of the system if a guard ring increases the capacitance to the line of metal work of the lowest insulator to 0.3 C.

If you double the impedance of a transmission line you will double the inductance per unit length. T or F. Can you explain why????

Please provide Handwritten answer

For the circuit shown in Figure 7.6, determine apparent power S, real power P, reactive power Qand power factor PF. Also, draw the power triangle. The source is 240 volts, XC = −j200 Ω,R = 75 Ω.
