  • I am a Youtuber & I am a Blogger too. My channel name is yuvi - study point.


  • The link of my channel is given below ~

  • In this Blogger site, we are going to learn about different Engineering subjects, different study materials, different subjects, and their important topics, etc.
  • For example ~ Maths, Physics, Power system, Power electronics, Electrical drives, Engineering maths, Electrical technology, About Different relays, Sensors & transducers, Control panels of electrical and automation, About different projects & technologies, etc.
  • Please share my Blogger site if you guys really found my explaining skills easier than others.
  • I would just love to give you guys more and more information.
  • This is my MAIL ID ~ yuvikasinghnov26@gmail.com, you guys can send me your problems related to subjects. So that I can help you and make your vision more clear on your subjects.

NBFM & WBFM (Narrow band frequency modulation & Wide band frequency modulation) simple explanation. By Yuvi - Study Point

Hey everyone, today we are going to learn about NBFM & WBFM (Narrowband frequency modulation & Wideband frequency modulation) in simple or easy way. So, without wasting any time lets get started. The information about NBFM & WBFM When the spectrum's efficiency is important or it is required then we use NBFM (Narrowband frequency modulation) is used.  But when better signal quality is required or when it is important then we use WBFM (Wideband frequency modulation). The term NBFM is used for those applications where the modulation index is less than or equal to 1. And the term WBFM is used for those applications where the modulation index is greater than or equal to 1. Now, let's see more difference between Narrow band frequency modulation(NBFM) and Wideband frequency modulation(WBFM). The term narrow-band and wide-band refer to the actual radio channel bandwidth. The purpose or advantage of using NBFM (Narrowband frequency modulation) The purpo...

Merz Price Differential Protection of Alternator. By Yuvi - Study Point

Hey everyone, today we are going to learn about Merz price differential protection of alternator. So, without wasting any time lets get started. Currents at the two ends of the protected section are compared in this scheme of differential protection of alternators. under the normal operating conditions, these currents are equal. But when a fault occurs in the protected section these currents become unequal. The most common system which is used for the protection of the stator winding faults employs circulating-current principle. Phase to phase fault and phase to earth fault, these are the two types of faults which occur in an alternator stator.  And through the operating coil of the relay, the difference of the currents under fault conditions is arranged to pass. And after this, the relay closes its contact to isolate its protected section. Or we can say to isolate its healthy section from the faulty section. And this form of protection is also known as Merz- pric...

Corona effect in transmission lines.| Explanation by Yuvi - Study Point

You all have heard about the Corona effect in transmission lines, now understand it in a simple way. This effect is a phenomenon which is associated with all transmission lines. At certain conditions, the electric field closer or near the energized conductors or components produces a tiny electric discharge or we can say corona which causes the surrounding air to ionize. And due to this ionization of surrounding air molecules of conductors, a luminous glow with hissing noise is produced which is known as Corona effect. Between the transmission lines, air act as a dielectric medium or we can say that air act as an insulator between current-carrying conductors. Between the conductors, voltage induces and if this voltage is of alternating nature then charging current will flow between the conductors. And the voltage of this transmission line and electric field intensity increases because of this charging conductor. There is a predetermined value of the electric field inten...
