Sequence Networks Unsymmetrical Faults: The analysis of an unsymmetrical fault by symmetrical components method can be conveniently done by drawing sequence networks. A Sequence Networks Unsymmetrical Faults of a particular…
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…
Requirements of Satisfactory Electric Supply Connection: The Electric Supply Connection in India is 3-phase a.c. operating at a frequency of 50 Hz. The power station delivers power to consumers through…
Economic Choice of Conductor Size: The cost of conductor material is generally a very considerable part of the total cost of a transmission line. Therefore, the determination of proper Conductor…
