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 as the line length increases.…
Transmission Lines and Waveguides: As we know already that, γ is a complex number of Transmission Lines and Waveguides which can be expressed as The real part α is called the attenuation constant and the…
Long Transmission Line: For lines over 250 km, the fact that the parameters of a line are not lumped but distributed uniformly throughout its length, must be considered. Figure 5.10 shows one phase and the…
Medium Transmission Line: For lines more than 100 km long, charging currents due to shunt admittance cannot be neglected. For lines in range 100 km to 250 km length, it is sufficiently accurate to lump…
Voltage Regulation of Transmission Line: Voltage Regulation of Transmission Line is defined as the rise in voltage at the receiving-end, expressed as percentage of full load voltage, when full load at a specified power factor…
Equivalent Circuit of Short Transmission Line | Phasor Diagram of Short Transmission Line: For Short Transmission Line of length 100 km or less, the total 50 Hz shunt admittance (jωCl) is small enough to be negligible…
Introduction to Power Transmission Line: Introduction to Power Transmission Line deals primarily with the characteristics and performance of transmission lines. A problem of major importance in power systems is the flow of load over transmission…
What is Load Curve?: Load drawn by consumers is the toughest parameter to assess scientifically. The magnitude of the load, in fact, changes continuously so that the load forecasting problem is truly a statistical one.…
Salient Pole Synchronous Generator: A Salient Pole Synchronous Generator, as shown in Fig. 4.29, is distinguished from a round rotor machine by constructional features of field poles which project with a large interpolar air gap.…
Phasor Diagram of Synchronous Motor: The Phasor Diagram of Synchronous Motor is the most important element of a power system. It converts mechanical power into electrical form and feeds it into the power network or,…
