Overhead vs Underground System: The distribution system can be Overhead vs Underground System. Overhead lines are generally mounted on wooden, concrete or steel poles which are arranged to carry distribution…
Insulating Materials for Underground Cables: The satisfactory operation of a cable depends to a great extent upon the characteristics of insulation used. Therefore, the proper choice of Insulating Materials for…
Mechanical Principles in Transmission Lines: Mechanical Principles in Transmission Lines design should depend to some extent on the importance of continuity of operation in the line under consideration. In general, the…
Corona: When an alternating potential difference is applied across two conductors whose spacing is large as compared to their diameters, there is no apparent change in the condition of atmospheric…
Types of Insulators in Transmission Lines: The overhead line conductors should be supported on the poles or towers in such a way that currents from conductors do not flow to…
Introduction to Overhead Line: Electric power can be transmitted or distributed either by means of underground cables or by overhead line. The underground cables are rarely used for power transmission…
Economic Choice of Transmission Voltages: It has been shown earlier here that if transmission voltage is increased, the volume of conÂductor material required is reduced. This decreases the expenditure on…
Economic Choice of Conductor Size: The cost of conductor material is generally a very considerable part of the total cost of a transmission line. Therefore, the determination of proper Conductor…
