## Use of Bundled Conductors in Transmission Line

Use of Bundled Conductors in Transmission Line: A Bundled Conductors in 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 ≈ […]

## Effect of Earth on Capacitance of Transmission Line

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

## 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 3 phase line with Equilateral Spacing

Capacitance of 3 phase line with Equilateral Spacing: Figure 3.5 shows a Capacitance of 3 phase line with 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 Since […]

## Capacitance of Two Wire Line

Capacitance of Two Wire Line: Consider a Capacitance of 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 be written […]
