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

Subject and UNIT: Transmission and Distribution: Unit I: Transmission Line Parameters

he transmission lines transmit bulk power with relatively high voltage. Electromagnetic and electrostatic fields are produced by these lines having sufficient magnitude.

Subject and UNIT: Transmission and Distribution: Unit I: Transmission Line Parameters

Consider the arrangement of conductors shown in the Fig. 1.33.1.

Subject and UNIT: Transmission and Distribution: Unit I: Transmission Line Parameters

Consider the arrangement of conductors shown in the Fig. 1.33.1.

Subject and UNIT: Transmission and Distribution: Unit I: Transmission Line Parameters

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

Subject and UNIT: Transmission and Distribution: Unit I: Transmission Line Parameters

The calculation of capacitance in case of conductors in three phase system which are not equally spaced is difficult. If the line is untransposed the capacitances of each phase to neutral is not same.
