Sensitivity Factor in Power System: A security analysis program is run in a load dispatch centre very quickly to help the operators. This can be attempted by carrying out an…
Capacitance of Two Wire Line: Consider a Capacitance of Two Wire Line shown in Fig. 3.3 excited from a single-phase source. The Capacitance of Two Wire Line develops equal and…
AC Resistance and DC Resistance Relation: Though the contribution of line resistance to series line impedance can be neglected in most cases, it is the main source of line power…
Compensating Winding in DC Machine: Compensating Winding in DC Machine - It was seen from earlier section, that armature reaction causes the flux density wave to be so badly distorted…
Armature Reaction in DC Machine: When the armature of a dc machine carries current, the distributed armature winding produces its own mmf (distributed) known as armature reaction in DC Machine.…
EMF and Torque Equation of DC Machine: EMF and Torque Equation of DC Machine - It was shown in Sec. 5.2 (Fig. 5.14 (a)) that in a dc machine the…
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…
Torque in Round Rotor Synchronous Machine: Torque in Round Rotor Synchronous Machine - When the stator and rotor windings of a machine both carry currents, they produce their own magnetic…
