The voltage of an electromagnetic wave propagating in a coaxial cable with uniform characteristic impedance is V() = e-l+jwt where is the distance along with the length of the cable in meters, y = 0.1 + j40 m-¹ is the complex propagation constant, and w = 2π x 10⁹ rad/s is the angular frequency. Find the absolute value of the attenuation in the cable in dB/meter.

The weight of the conductor in the transmission line is 1.5 kg/m. The span of the line is 100 m. The maximum tensile strength of the conductor is 4000 kg. Calculate the seg assuming a factor of safety of 2.

b) Ghana Grid Company (GRIDCo) designed a short transmission line using the A, B, C, D line constant of a transmission line parameters in its analysis. The engineering planning department came up with the design and said that when they computed the line performance using the equation AD – BC the answer was equal to 1.As an employee at the Ministry of Energy (MoEn) having oversight responsibility over GRIDCo, how would you accept the answer and recommend the Government of Ghana (GoG) to go ahead to implement the short transmission line?

How do you design transmission line and verify it?
