Electrical Design of Overhead Lines

Capacitance of Three Phase Overhead Line

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 spacing and unsym­metrical spacing. 1.Symmetrical Spacing: Fig. 9.24 shows the three con­ductors A, B and C of the 3-phase overhead …

Flux Linkage

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. We shall discuss two important cases of flux linkages. 1.Flux linkage due to a Single Current Carrying Conductor: Consider a …
