Transmission Line Parameters
Subject and UNIT: Transmission and Distribution: Unit I: Transmission Line Parameters
Bundled conductors are used in EHVAC transmission lines which control the voltage gradiant at the surface of the conductor.
Subject and UNIT: Transmission and Distribution: Unit I: Transmission Line Parameters
When a conductor carries a steady or d.c. current, this current is uniformly distributed over the whole cross-section of the conductor.
Subject and UNIT: Transmission and Distribution: Unit I: Transmission Line Parameters
The current distribution may be non-uniform because of another effect known as proximity effect.
Electromagnetic - Electrostatic Effect - Steps for Reducing Telephone Interference

The method of images can be applied for determining the capacitance of this line to take into consideration the effect of earth.
Subject and UNIT: Transmission and Distribution: Unit I: Transmission Line Parameters
The conductors of any one bundle are in parallel and charge per bundle is assumed to divide equally between the conductors of bundle.
Transmission Line Parameters
