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…
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.…
Constants of a Transmission Line: A transmission line has resistance, inductance and capacitance uniformly distributed along the whole length of the line. Before we pass on to the methods of…
Sag in Overhead Transmission Lines: While erecting an Sag in Overhead Transmission Lines, it is very important that conductors are under safe tension. If the conductors are too much stretched…
Potential Distribution Over Suspension Insulator String: A string of suspension insulator consists of a number of porcelain discs connected in series through metallic links. Fig. 8.10 (i) shows 3-disc string…
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…
Conductor Material Used for Transmission and Distribution: The conductor is one of the important items as most of the capital outlay is invested for it. Therefore, proper choice of material…
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…
