Capacitance of Single Core Cable: A Capacitance of Single Core Cable can be considered to be equivalent to two long co-axial cylinders. The conductor (or core) of the cable is…
Long Transmission Line Voltage: It is well known that line constants of the transmission line are uniformly distributed over the entire length of the line. However, reasonable accuracy can be…
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…
