Difference between Rated,Nominal and Operating Voltage
In this post, we will discuss the difference between rated, nominal, and operating voltage. Operating at the designed operating voltage enhances the equipment’s life. There … Read more
Electrical Insulation Classes | Classification of Insulating Materials
The life of electrical insulating materials gets adversely affected by the rise in temperature. Average insulation life gets halved for every 10° C increase in temperature. Therefore, the classification … Read more
Harmonics and Harmonic Frequency in AC Circuits
Harmonics refers to the additional frequencies that are generated alongside the fundamental frequency of a waveform. These frequencies are typically unwanted and can cause distortion … Read more
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 … Read more
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 … Read more
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 … Read more
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 … Read more
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. … Read more
Harmonic Restraining in Differential Protection
The differential relay is used for the protection of the transformer, alternator, and large-rating HT motor. The differential protection scheme is also known as zone … Read more
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 … Read more
