## Bundled Conductors Transmission Line

Bundled Conductors Transmission Line: A Bundled Conductors Transmission Line is shown in Fig. 3.13. The conductors of any one bundle are in parallel, and it is assumed that the charge per bundle divides equally among the conductors of the bundle as D12 ≫ d. Also     D12 — d ≈ D12 + d ≈ […]

## Effect of Earth on Transmission Line Capacitance

Effect of Earth on Transmission Line Capacitance: In calculating the Effect of Earth on Transmission Line Capacitance, the presence of earth was ignored, so far. The effect of earth on capacitance can be conveniently taken into account by the method of images. Method of Images The electric field of transmission line conductors must conform to […]

## Capacitance of a Three Phase Line Unsymmetrical Spacing

Capacitance of a Three Phase Line Unsymmetrical Spacing: Figure 3.7 shows the three identical conductors of radius r of a Capacitance of a Three Phase Line Unsymmetrical Spacing. It is assumed that the line is fully transposed. As the conductors are rotated cyclically in the three sections of the transposition cycle, correspondingly three expressions can […]

## Capacitance of a Three Phase Line Equilateral Spacing

Capacitance of a Three Phase Line Equilateral Spacing: Figure 3.5 shows a Capacitance of a Three Phase Line Equilateral Spacing composed of three identical conductors of radius r placed in equilateral configuration. Using Eq. (3.2) we can write the expressions for V ab and Vac as   Adding Eqs. (3.8) and (3 9), we get […]

## Capacitance of a Two Wire Line

Capacitance of a Two Wire Line: Consider a Capacitance of a Two Wire Line shown in Fig. 3.3 excited from a single-phase source. The line develops equal and opposite sinusoidal charges on the two conductors which can be represented as phasors qa and qb so that qa = — qb. The potential difference Vab can […]

## Potential Difference between Two Conductors

Potential Difference between Two Conductors of a Group of Parallel Conductors: Potential Difference between Two Conductors – Figure 3.2 shows a group of parallel charged conductors. It is assumed that the conductors are far removed from the ground and are sufficiently removed from each other, i.e. the conductor radii are much smaller than the distances […]

## Electric Field of a Long Straight Conductor

Electric Field of a Long Straight Conductor: Electric Field of a Long Straight Conductor – Imagine an infinitely long straight conductor far removed from other conductors (including earth) carrying a uniform charge of q coulomb/metre length. By symmetry, the equipotential surfaces will be concentric cylinders, while the lines of electrostatic stress will be radial. The […]
