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…
Use of Power Capacitor: In most of the industrial applications, the power requirements are reactive in nature and a lagging current is drawn from the power lines. This requires additional…
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)…
Short Circuit in Power System: Whenever a fault occurs on a network such that a large current flows in one or more phases, a Short Circuit in Power System is…
Bus Bar Arrangement in Power Station: When a number of generators or feeders operating at the same voltage have to be directly connected electrically, bus-bars are used as the common…
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.…
Mechanical Principles in Transmission Lines: Mechanical Principles in Transmission Lines design should depend to some extent on the importance of continuity of operation in the line under consideration. In general, the…
