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…
Principle of Induction Motor | Torque Slip Characteristic: Principle of Induction Motor has not been introduced so far. Consider a cylindrical rotor machine with both the stator and rotor wound…
Torque Equation of Synchronous Motor: Figure 5.36 shows a Torque Equation of Synchronous Motor with a round rotor. The rotor is initially stationary with fixed north-south poles created by dc…
Rotating Magnetic Field: Rotating Magnetic Field - It was seen earlier that the sinusoidal current in any phase of an ac winding produces a pulsating mmf wave in space whose…
Tap Changing Transformer | Off Load Tap Changer |On Load Tap Changing: Tap Changing Transformer -Voltage variation in power systems is a normal phenomenon owing to the rapid growth of…
Three Winding Transformer: Three Winding Transformer may be built with a third winding, called the tertiary, in addition to the primary and secondary. Various purposes which dictate the use of…
Parallel Operation of Transformer: When the load outgrows the capacity of an existing transformer, it may be economical to install another one in parallel with it rather than replacing it…
