Sequence Impedances of Transmission Lines: Sequence Impedances of Transmission Lines - Figure 10.9 shows the circuit of a fully transposed line carrying unbalanced currents. The return path for In is…
Selection of Circuit Breaker: There are two types of Selection of Circuit Breaker ratings which require the computation of SC current are: (i) rated momentary current and (ii) rated symmetrical…
Short Circuit Current Computation through Thevenin Theorem: An alternate method of computing Short Circuit Current Computation is through the application of the Thevenin theorem. This Short Circuit Current Computation method…
Waveform of a Short Circuit Current on Transmission Line: Let us consider the Short Circuit Current on Transmission Line. Certain simplifying assumptions are made at this stage. The line is…
Construction of Induction Motor and Types of Rotor in Induction Motor: The stator of an Construction of Induction Motor is similar to that of a synchronous machine and is wound…
Brushless DC Motor: The term Brushless DC Motor is applied to many configurations of ac synchronous motors in which semiconductor control is used to control stator currents such that maximum…
AC Winding: Ac winding are generally of a 3-phase kind because of the inherent advantages of a 3-phase machine. The armature coils must be connected to yield balanced (equal in…
DC Motor Losses and Efficiency: The Losses and Efficiency of a transformer have been studied in earlier lesson. As in the case of transformers, it is more accurate to determine…
