Why Induction Motor is called Asynchronous Motor?
An induction motor is called an asynchronous motor because the actual speed of the motor is not equal to the synchronous speed of the motor. The synchronous
Why the Slip never Zero in an Induction Motor?
A rotating magnetic field is produced when the three-phase supply is fed to the stator. The magnetic field travels the air gap length and cuts
What is Synchronous speed? Relationship between speed and Frequency
Synchronous Speed When three phases which are 120 degree-electrical apart are fed to the stator winding of the induction motor, a rotating magnetic field is
Slip Speed in an Induction Motor
A rotating magnetic field is produced when three phase supply is fed to stator of an induction motor. The rotating magnetic field has constant magnitude
What is Hysteresis Loop? Its Importance
A hysteresis loop is a graph in a four-quadrant that shows the relationship between the induced magnetic flux density B and the magnetizing force H.
Harmonic Restraining in Differential Protection
Harmonic restraining in differential protection is a technique used in transformer protection to prevent false tripping during inrush or over-fluxing conditions by detecting and blocking
Single Phase Transformer and Application of Single Phase Transformer
The transformer transforms voltage from one level to another without changing the power and frequency. The transformer is static electrical equipment, and it does not
Effects of Harmonics on Capacitors | Interaction of Harmonics with Capacitors
The adverse Effects of Harmonics on Capacitors comprise series and parallel resonance, heating, overloading, and increased dielectric loss. The harmonics also cause a severe problem of
Ideal Transformer-Properties, Phasor Diagram, Working
What is an Ideal Transformer? An ideal transformer is free from all losses. It has zero copper and iron loss and zero leakage flux, and
Effects of Harmonics on Power Cables
Power cables carry power from the supply source to the load point. They have DC resistance, which depends on their size. When current flows through
