    Outstanding. There are many analogies like pulling a wagon on a rail road by a horse coupled inline with the wagon for unity PF loads and away from the wagon for lagging PF loads. When you pull inline you have no losses and more you are away from the wagon you have losses accordingly.

    really it's a useful lecture
    Now I clearly
    1/differentiate between POWER
    FACTOR & EFFICIENCY
    2/ I knew that the phase terminal in sockets outlets always the right hole outlet...
    although I'm not convinced that the logic of right has five letters and phase also has five letters

    At end you said about phase and neutral pins.in my prospective that is wrong because for AC phase and neutral are changing per every 0.02 sec.so no problem with phase shifting.it is mandatory for DC voltage because + and - . direction is only one side.👍

    Need to explain more about reactive power(Q) that you need to reduce to make the power factor closer to unity if the load is inductive for example. Power triangle is the simplest for power factor explanation using the ratio between P/S.

  • @akshayc4145
    @akshayc4145 5 ปีที่แล้ว +1

    Sir,
    Then how a capacitor improves this.....you can say it act as a mediator who supplies apparent power to an inductive load..so that the main supply transmission not gets affected...
    But consider a pure capacitive load(never exist in practical..but can be set it) ..how it raises power factor above one..
    ..by your anology wrt online shopping...the consumer (capacitor) returns all the products he bought + some of the products he already got...is that the scene..
    you can explain what happens in a practical RLC load...nd what happens to the remaining energy
    ...
    Good effort nice video...
    plz reduce the pop ups(if cannot plz reduce the font size or..show it in intervels)
    ..provide a clean interface (like khan,..etc)..now its look like a online shopping tv ad.
    you provide superb quality content thats what all necessary..no need of gimmicks..
    Suggestion
    Content quality is good.. But video quality needs improvement especially in the audio side..needs some sort of boosting and noice removel...you seems to use high tech...the use of projector+board is nice..in this setup..audio needs improvement
    The stay focus thing is good but need to do in a more initiative way..
    Thank you..

Last month my pf was .610 , after adding there is minimal improvement in a day if i run my company it increases by 3 and by night it falls 5 points . helpme i paid a penalty of 18000 last bimonthly bill.40 days since adding capacitor now my reading stands . 704

    @ratikantamahapatra8847 5 ปีที่แล้ว

    sir you have mentioned two sinusoidal wave ( current and voltage) here ...a sinusoidal wave have + and - part ...it is actually alternating the direction ,right? and itis happens due to relative motion between magnetic field and conductor( Generator)....my confusion is that you said that it happens due to inductor ...

    • @akshayc4145
      @akshayc4145 5 ปีที่แล้ว

      What he says is about..power
      Simply,
      Power = Volt x current
      In resistive loads..volt sin wave and curr. Sin wave are in phase..ie both gets their positive half and neg. Half at same time..
      If we calculate power
      + Ve half (+V) x (+I) = + P
      -Ve half (-V) x (-I) = +P
      The power always positive that means it flows in one direction ie..source to load in case of resistive load..
      now you check the video, from the graph of inductive load you can find out what happens there..
      Gd day

  • @pvbabu6241
    @pvbabu6241 6 ปีที่แล้ว

    Sir u have said that the transmission voltage is in the form of 11kv 33kv this is due to 10% for losses then at secondary distribution ie from substations 11kv line is given to the 11kv transformer then in this case they may also have losses then why the out lines from substation is exactly 11kv and given to the transformer rating of 11kv

  • @sureshbabu-tj8fl
    @sureshbabu-tj8fl 6 ปีที่แล้ว +6

    Sir we need more clarity. P.f means "energy loss is measured in terms of power factor" your explanation is a text book theory
    But in practical we need to reduce this to save energy by maintaining nearly unity power factor

    • @ThePiSquareAcademy
      @ThePiSquareAcademy  6 ปีที่แล้ว +2

      Yes.! we need to reduce this to save energy. (co-relation: if more returns to the seller then, transportation loss and during that time he could have provided that energy to another user.)
