Performance of Single Phase Short Transmission Line Voltage: As stated earlier, the effects of line capacitance are neglected for a short transmission line. Therefore, while studying the performance of such a line, only resistance and…
Classification of Overhead Transmission Lines: The important considerations in the design, operation and Classification of Overhead Transmission Lines are the determination of voltage drop, line losses and efficiency of transmission. These values are greatly influenced…
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…
