      Hello sir I am just curious on an explanation video that you have made that is the moving train beeing mesurered ,do you know who invented it
      Because I have found some papers of my grandfather's and they are the blueprint of them so I'm trying to see if someone is claiming his invention from 1960's

      1st, this formmula F=mf was invented long back and not 60 years back.
      2nd any invention patent period is only 20 years. After that any body can use it.
      In automatic washing machin also, mass of the cloth is measured just after starting the machine.
      So formuls is known but implementation is quite difficult.
      Different engine manufacturers follow different techniques To measure and control.
      I studied 1000s of books, paper , articles, documents, discussion with experts, my own analyses, my own project in last 40 years. So I can not tell that which knowledge I got from where.

      For example 30 amp unbalance h to Kya vo ground mein waste ho jata h
      Sir

      B phase 70. amps h to kitna amps unbalance hoga aur Kya ye unbalance ground me chla jaega earthing wire se aur waste ho jayega

    Great explanation! Where to put or location of the AFDD in panel board? is it before or after the main mcb breaker?

    • @GKAgrawal2
      @GKAgrawal2  3 ปีที่แล้ว +1

      AFDD has build in MCB. Any way it will work, you put before or after MCB. But I will contact manufacturer and ask them, where to put.

    • @GKAgrawal2
      @GKAgrawal2  3 ปีที่แล้ว +1

      I contacted the manufacturer of the AFDD shown in this video. Their expert replied that, this AFDD can replace the present MCB at the incomer.
      I feel that if you want, you can retain existing MCB also. AFDD can be connected before the MCB.

    Hello, what is the RSSI signal and how to extract it from the sinusoidal signal of the network. Can I use the fast furier transform, or use the two channels of the oscilloscope through the mathematical function of subtracting the sine current from the receiver current? I understand that this is a signal extracted from the waveform of the current consumed by the receiver?!

      Good question. 4 to 20 mA signal transmission key liyey use hota hai. Adhik tar sensor key liyey. Yeh DC current hoti hai. Voltage ki jagah current use karney sey noise problem less hoo jathi hai.

    I have a long-pending query.
    1. For a balanced 3 Phase, positive phase sequence components current in Fig. (or diagram) show the direction of rotation in ANTI-CLOCKWISE direction and mention RYB. But, in moving ANTI-CLOCKWISE direction, sequence to face first IR1 further IB1 and at last IY1
    2. Similarly for balanced negative sequence components current in Fig. (or diagram) show the direction of arrow ANTI-CLOCKWISE direction and mention RBY. But, in moving ANTI-CLOCKWISE, sequence to face IR2 further IY2 and at last IB2
    It is not understandable.
    Till now, in every power system book, this is mentioned. For your ready reference, Page 424 from Power System VK Mehta.

      @GKAgrawal2  4 ปีที่แล้ว

      You are asking as if you are complaining to some government or some supplier of some item purchased by you. Note that this is free teaching class.
      Any way, for negative sequence, direction will be clock wise, and not anti clock wise.
      Further I am unable to understand that what is not clear to you.

    Sir 100 watt bulb ka practically 38 ohm's
    But theoretical 484 ohm aisa kyu
    P=V^2/R. P= V^2/R
    = 220^2/38. = 220^2/484
    =1273 watt = 100 watt
    Aisa kyu
