Circuit Constants of a Transmission Line: In any four terminal network, the input voltage and input current can be expressed in terms of output voltage and output current. Incidentally, a…
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…
Medium Transmission Line Voltage: In short transmission line calculations; the effects attic line capacitance are neglected because such lines have smaller lengths and transmit power at relatively low voltages (<20…
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…
Line Support: The supporting structures for overhead line conductors are various types of poles and towers called line support. In general, the line supports should have the following properties :…
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…
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…
