In a short transmission line, the line charging current value is smaller than a medium transmission line. tap changing transformer Calculate the weight due to ice on a transmission line where the Total weight of conductor = 3.2 Kg/m, actual weight of conductor = 1.4 Kg/m, and weight due to wine %3D %3D 0.4 Kg/m. In a short transmission line, the line charging current value is smaller than a medium transmission line.

1/ Power loss due to corona is: a. Inversely proportional to frequency. b. Proportional to frequency. c. Frequency does not effect. d. All these answers are wrong. 2/ We prefer High voltage DC (HVDC) transmission system than High Voltage AC transmission system according to the cost, when: a. The distance of the line is more than B00 km. b. The distance of the line is less than 300 km. c. The distance of the line is equal to 300 km. d. All the above answers are wrong. 3/ HVDC Transmission has lower corona losses than HVAC Transmission because: a. HVDC Transmission tower is less height than HVAC Transmission tower. b. HVDC Transmission system work with zero frequency than HVAC Transmission system of 50 Hz. c. HVDC Transmission currents is uniform distributed in the all cross section of the system conductors than HVAC Transmission due to skin effect. d. All of the above answers are wright.

A 50 transmission line is to be connected to a 72 load through a 1/4 quarter wave matching transformer. (a) What must be the characteristic impedance of the transmission line that is used to form the quarter wave transformer? (b) If the frequency of operation is 7 MHz and the phase velocity through the quarter wave section is 2c/3, what is the length of the quarter wave section? You may assume the transmission line forming the quarter wave section is lossless.

With a neat diagram show the reflections occurring in a transmission line. Hence explain the concepts of Reflection co-efficient and VSWR associated with it.

Please have the solution in clear writing

Explain how you would create a pcb design for transmission line?

Ql: Choose the correct answer for the following; • Wind turbine is considered one of the prime mover types. (T or F) • Transmission lines are used to (transmit and distribute or distribute and transmit) • The The objective of using batteries is to The alternator converts .... of the prime mover energy or electrical energy into mechanical energy) • Nuclear power station can be produced a .... For the transmission line parameters, the shunt capacitance is the responsible of .... (charging currents or discharging currents) • In short transmission line, the conductor can carry up to The other name of geometric mean radius is The electric field lines originate from. The effect of the capacitance is proportional to the length of transmission line (T or F) • The symbol ɛ represents the .the electrical power generated. and is one of the sources of renewable electrical energy. (water or fuels) energy when the wind stops. (supply or consume) (mechanical energy into electrical amount of…
