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.…
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,…
What is Skin Effect and Proximity Effect?: What is Skin Effect and Proximity Effect? - The distribution of current throughout the cross-section of a conductor is uniform only when DC is passing through it. On…
AC Resistance and DC Resistance Relation: Though the contribution of line resistance to series line impedance can be neglected in most cases, it is the main source of line power loss. Thus while considering transmission…
Bundled Conductors in EHV Transmission Lines: It is economical to transmit large chunks of power over long distances by employing EHV lines. However, the line voltages that can be used are severely limited by the…
Inductance of Double Circuit Three Phase Line: It is common practice to build double circuit three phase Line so as to increase transmission reliability at somewhat enhanced cost. From the point of view of power…
Inductance of Three Phase Line with Unsymmetrical Spacing: The basic equations developed can, however, be easily adapted to the calculation of the Inductance of three phase line. Figure 2.10 shows the conductors of a three…
Inductance of Composite Conductor Lines: Future 2.6 shows such a single-phase line comprising inductance of composite conductor lines A and B with A having n parallel filaments and B having m' parallel filaments. Though the…
Flux Linkage of n Parallel Conductors Carrying Current: As shown in Fig. 2.5, consider a group of n parallel conductors carrying current I1, I2 ,..., In whose sum equals zero. Distances of these conductors from…
ACSR Conductor (Aluminium Conductor Steel Reinforced): ACSR Conductor - So far we have considered transmission lines consisting of single solid cylindrical conductors for forward and return paths. To provide the necessary flexibility for stringing, conductors…
