Compensation in Power System Articles: What is Compensation in Power System: Introduction to Compensation in Power System – For reduction of cost and improved reliability, most of the world’s electric…
Measurement of Power Articles: Bolometer: Bolometric measurements are based on the dissipation of RF power in a small temperature sensitive resistive element, called a Bolometer. This bolometer may be a…
Transmission Line Overvoltage Protection: Transmission Line Overvoltage Protection against natural or lightning overvoltages and minimizing the lightning overvoltages are done by suitable line designs, providing guard and ground wires, and…
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…
Switching Surges in Transmission Line: Till the time when the transmission voltages were about 220 kV and below, over-voltages due to lightning were of very high order and overvoltages generated…
Transmission of Waves at Transition Points: Whenever there is an abrupt change in the parameters of a transmission line, such as an open circuit or a termination, the travelling wave…
Sequence Impedance of Power System: Each element of power system will offer impedance to different phase sequence components of current which may not be the same. For example, the impedance…
Unsymmetrical Faults on Three Power System: Those faults on the power system which give rise to unsymmetrical fault currents (i.e. unequal fault currents in the lines with unequal phase displacement)…
