Starting Methods of Induction Motor: Starting Methods of Induction Motor - At the time of starting the motor slip being unity, the load resistance with reference to the approximate circuit model of Fig. 9.23 is…
Three Phase Rectifiers: Three-Phase Half-Wave Rectifier : Figure 9.11 illustrates a circuit for a 3-phase half-wave rectifier. The three diodes are connected to the three phases of a 3-phase transformer star-connected secondary. Neutral point N…
AC Series Motor: A series motor can be run from either dc or ac (single-phase) supply provided that both stator and rotor cores are laminated to limit the iron-loss. Figure 10.43 is the cross-sectional view…
Conductor Semiconductor and Insulator: Bonding Forces Between Atoms: Whether a material is a Conductor Semiconductor and Insulator depends largely upon what happens to the outer-shell electrons when the atoms bond themselves together to form a…
Load Frequency Control with Generation Rate Constraint (GRC): Load Frequency Control with Generation Rate Constraint (GRC) - The Load frequency Control problem discussed so far does not consider the effect of the restrictions on the…
Fibre Optic CRT Recording Oscilloscope: Fibre Optic CRT Recording Oscilloscope - The familiar CRT oscilloscope has an extremely HF response, but permanent records, normally photography of the screen, cannot be taken, since they are time…
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 for three phases, modem practice…
Effect of Negative Feedback on Input Impedance: High input impedance is always desirable in an amplifier as it will not load the preceding stage or the input voltage source. Such a desirable characteristic can be…
Step up Chopper - Definition, Circuit Diagram and its Working Principle: In a step-down chopper the output voltage lies between zero and supply voltage. However, there are techniques by which the output of a chopper…
Subsystems of Thermal Power Plant: The Subsystems of Thermal Power Plant are the auxiliary plants required for the plant for its proper operation and for the increase of their efficiency. Some of the sub systems…
