Power Flow Equation of Synchronous Generator: Power Flow Equation of Synchronous Generator - The flow of active and reactive power in a synchronous link will now be studied. The approach will be analytical and armature…
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 open while the primary is…
Phasor Diagram of Transformer: For the approximate equivalent circuit of Phasor Diagram of Transformer is shown in Fig. 3.16(b) The phasor diagram corresponding to this equation is drawn in Fig. 3.17(a) for the lagging power…
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 in supplying 2-phase electric arc…
Phase Control of Three Phase Induction Motor: Figure 11.44 shows the schematic representation of Phase Control of Three Phase Induction Motor. Two thyristors are connected in antiparallel in each line. The firing sequence of the…
Per Unit System: While carrying out the analysis of electrical machines (or electrical machine systems), it is usual to express voltage, current, VA and impedance in Per Unit System (or percentage) of the base or…
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 with a single larger unit.…
