Three Phase Service Cable: In practice, underground cables are generally required to deliver 3-phase power. For the purpose, either three-core cable or three single core cables may be used. For…
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…
Performance of Three Phase Short Transmission Line: For reasons associated with economy, transmission of electric power is done by Three Phase Short Transmission Line. This system may be regarded as…
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…
Comparison of AC Transmission and DC Transmission: The electric power can be transmitted either by means of d.c. or a.c. Each system has its own merits and demerits. It is,…
