Ideal Transformer on Load: Transfer of energy from one circuit to another circuit through mutual induction is widely utilized in power systems. This purpose is served by Ideal Transformer on…
Mutual Inductance of Coupled Circuits: Mutual Inductance of Coupled Circuits - A voltage is induced in a coil when there is a time rate of change of current through it.…
Effects of Harmonics: The relationship between line and phase quantities for wye and delta connections as derived earlier are strictly valid only if the source voltage is purely sinusoidal. Such…
Working Principle of Relay Articles: Induction Relay Torque Equation : In Induction Relay Torque Equation, Two magnetic fluxes Φ1 and Φ2 differing in time phase penetrate through a disc. These alternating fluxes…
Power Swings in Power System Protection: The impedance measured or seen by a distance relay during normal load is shown in Fig. (5.29). Normally this would be outside the tripping…
Differential Relay Application: The principle of operation depends on a simple circulating current principle where the difference of the currents of the two CTs flows through the relay under normal…
Switched Reluctance Motor: The switched reluctance motor (SRM) has both salient pole stator and rotor, like variable stepper motor, but they are designed for different applications, and therefore, with different…
Stator Voltage Control of Induction Motor: By reducing Stator Voltage Control of Induction Motor, speed of a high-slip induction motor can be reduced by an amount which is sufficient for…
