Ferranti Effect in Transmission Line: The effect of the line capacitance is to cause the no-load receiving-end voltage to be more than the sending-end voltage. The effect becomes more pronounced…
Performance of Short and Medium Transmission Lines Interview Questions and Answers: 1. What are the factors which govern the performance of a transmission line ? Ans. The factors governing the…
Series and Shunt Compensation of Transmission Lines: The performance of long EHV AC transmission systems can be improved by reactive compensation of series or shunt (parallel) type. Series capacitors and…
Performance of Power Transmission Articles: Equivalent Circuit of a Long Line : So far as the end conditions are concerned, the Equivalent Circuit of a Long Line can be established…
Control of Switching Overvoltage: The Control of Switching Overvoltage and power frequency may be controlled by energization of transmission lines in one or more steps by inserting resistances and withdrawing…
Power Frequency Overvoltages in Power Systems: The Power Frequency Overvoltages occur in large power systems and they are of much concern in EHV systems, i.e. systems of 400 kV and…
What is Series Compensation in Power System?: Series Compensation - A capacitor in series with a line gives control over the effective reactance between line ends. This effective reactance is…
Line Compensation in Power System: Line Compensation - Ideal voltage profile for a transmission line is flat, which can only be achieved by loading the line with its surge impedance…
