Which of the following is **not** a primary parameter of a transmission line?
Analysis & Theory
Impedance is a derived quantity; the primary parameters are R, L, C, and G (conductance).
The **resistance** of a transmission line depends on:
A
Conductor material and temperature
Analysis & Theory
Resistance varies with conductor material, length, cross-section, and temperature.
Which parameter accounts for **energy storage in the magnetic field** of a transmission line?
Analysis & Theory
Inductance represents the magnetic field energy storage in a line.
Capacitance between conductors of a transmission line increases with:
A
Increase in conductor spacing
B
Use of thicker insulation
C
Increase in conductor diameter
Analysis & Theory
Larger conductor diameter increases capacitance due to higher surface area.
Which parameter accounts for the **leakage current** in the insulation between conductors?
Analysis & Theory
Conductance (G) represents leakage through the dielectric material between the conductors.
The unit of **line inductance** is:
Analysis & Theory
Inductance is measured in Henries per kilometer (H/km).
The **capacitance** of an overhead transmission line depends mostly on:
B
Conductor spacing and height
Analysis & Theory
Capacitance is determined by the spacing between conductors and their height above the ground.
Which transmission line parameter is **frequency-dependent**?
Analysis & Theory
All parameters (R, L, C, G) vary with frequency due to skin effect and dielectric behavior.
Which method is used to calculate **inductance** of transmission lines?
Analysis & Theory
The Geometric Mean Distance (GMD) and Geometric Mean Radius (GMR) method is used to compute inductance.
Which of the following causes **losses** in transmission lines?
C
Resistance and Conductance
Analysis & Theory
Real power losses occur due to resistance (I²R) and leakage through conductance (G).
