Capacitance of Three Phase Line with Unsymmetrical Spacing

Capacitance of Three Phase Line with Unsymmetrical Spacing: Figure 3.7 shows the three identical conductors of radius r of a Capacitance of Three Phase Line with 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 …

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 …
