Capacitance of Three Phase Overhead Line: In a Capacitance of Three Phase Overhead Line, the capacitance of each conductor is considered instead of capacitance from conductor to conductor. Here, again two cases arise viz., symmetrical…

Capacitance of a Single Phase Two Wire Line: Consider a Capacitance of a Single Phase Two Wire Line consisting of two parallel conductors A and B spaced d metres apart in air. Suppose that radius…

Electric Potential Definition: The Electric Potential point due to a charge is the work done in bringing a unit positive charge from infinity to that point. The concept of electric potential is extremely important for…

Self GMD and Mutual GMD: Self GMD and Mutual GMD - The use of self geometrical mean distance (abbreviated as Self GMD) and mutual geometrical mean distance (Mutual GMD) simplifies the inductance calculations, particularly relating…

Inductance of 3 Phase Overhead Line: Fig. 9.8 shows the three conductors A, B and C of a Inductance of 3 Phase Overhead Line carrying currents IA, IB and IC respectively. Let d1, d2 and d3…

Inductance of Single Phase Two Wire System: A Inductance of Single Phase Two Wire System consists of two parallel conductors which form a rectangular loop of one turn. When an alternating current flows through such…

Flux Linkage: The inductance of a circuit is defined as the flux linkage per unit current. Therefore, in order to find the inductance of a circuit, the determination of flux linkage is of primary importance.…

Skin Effect in Transmission Lines: Skin Effect in Transmission Lines - When a conductor is carrying steady direct current (d.c.), this current is uniformly distributed over the whole X-section of the conductor. However, an alternating…

Constants of a Transmission Line: A transmission line has resistance, inductance and capacitance uniformly distributed along the whole length of the line. Before we pass on to the methods of finding these Constants of a…
