Capacitance of Three Phase Transmission Line with Equilateral Spacing

Capacitance of Three Phase Transmission Line with Equilateral Spacing: Figure 3.5 shows a Capacitance of Three Phase Transmission 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 Vab and Vac as Adding Eqs. (3.8) and (3 9), we get

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 Capacitance of Two Wire 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

Potential Difference between a and b

Potential Difference between Two Conductors

Potential Difference between a and b: 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 between them. The spacing commonly used in overhead power transmission lines

Electric Field Inside a Conductor

Electric Field Inside a Conductor

Electric Field Inside a 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 Electric Field Inside a Conductor at a distance y from
