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. These values are greatly influenced by the line constants R,L and … (Read More)

Performance of Single Phase Short Transmission Line Voltage: As stated earlier, the effects of line capacitance are neglected for a short transmission line. Therefore, while studying the performance of such a line, only resistance and inductance of the line are taken … (Read More)

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 consisting of three single Phase units, each wire transmitting one-third of … (Read More)

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 kV): However, as the length and voltage of the line increase, … (Read More)

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 obtained in line calculations for short and medium lines by considering … (Read More)

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 Circuit Constants of a Transmission Line is a 4-terminal network ; … (Read More)
