Synchronous Generator Ratings and Loss Dissipation: The Synchronous Generator Ratings and Loss Dissipation is its operating voltage, frequency, speed and kVA/MVA output at a specified power factor. In case of…
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…
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…
Phase Conversion in Transformer: Three Phase to Two Phase Conversion Transformer (Scott-T transformer or Scott Connection): Phase conversion from three to two phase is needed in special cases, such as…
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…
Autotransformer | Definition | Use of Auto transformer: So far two-winding transformers have been discussed wherein the windings are electrically isolated. When the primary and secondary windings are electrically connected…
Phasor Diagram of Transformer on No Load: Figure 3.5 shows the schematic diagram of a Phasor Diagram of Transformer on No Load with Two Winding, i.e. the secondary terminals are…
