With out connection just time pass vedio
Please check another video, connections also shown.
Hello, how can i chat with you?
You can Email me.
@@ganeshgc3285 hello where is your email address ?can write here
Sir conduct all experiment according to vtu syllabus🙏🏻🙏🏻
Hello sir Can you please share the experiment observation, calculations and results?
Can we get sumpner test manual....
Sir please do vedios of 21 scheme theory also fr 4th sem upcoming🙏🏻🙏🏻🙏🏻 please help EEE STUDENTS SIR
Show the connection from beginning
Make a more videos ❤
Thanks sir 🙏🏻
Thanks
Thank You ! Helped me understand the theory better
how is the rated current =7.5 amps?
Why we need to gradually increase the voltage at the primary winding and now supply the rated voltage at the first go only
That's a good point, actually we use auto transfer as a starter and always voltage to be applied gradually to avoid high inrush current at start. For more information you can reffer any text book.
The names of the transformers mentioned by you are need to be corrected according to the percentage tappings i.e. in place of teaser transformer it is to be mentioned Main transformer and vice versa.
Yes sir, your right. Thank you.
Hello @Ganesh, thanks for this session. Please, how did you arrive at 5 for both unity pf for leading and lagging under voltage percentage regulation?
hello sir note pdf link send karo
Thank you sir
👍👍👍

On grid induction generator 👍👌 very good lesson 🙏
Sir, can u send the manual?
send me your mail id
anastinsasini17@gmail.com
I need the readings can you please share in discription.?
Sir in Scott connection why can't we take a single load that means instead of two loads at two times switching at a time if we take a single with three terminals two phases and one neutral wire we connect then how can we connect
Two separate load means to demonstrate that we can connect 2 separate loads at secondary after conversion from 3 to 2 phases.
@@ganeshgc3285 kkk but in applications how can we connect two phase load two phases and one neutral wire if that load needs because in output there are 4 terminals are coming but if load neads 3 terminals 2 phases and one neutral
@@bandaruramana2119 Sir, what you said is right, but for more theories and explanation I suggest you to refer some standard books. Thank you.
@@ganeshgc3285 tq sir
Tq bro😘....may be helpful for tomorrow's exam if this experiment comes
can you send me the Em 1 & 2 manual soft copy OF THE SAME pdf or word mail id: muralipse@gmail.com

Siiiir
Explain better. Too fast for Americans
What is the value of resistance at 100%?
Nice 👍👍👍
Par sir aapne kitna load badhaya yeh nhi bataya
Do you have pdf of all that experiments about 3 phase transformers?
Nic sir
If you keep the voltage constant, the current will increase almost proportionately to the increase in torque load. As you increase the load, you can increase the supply voltage, and bring the current back down. Doubling the load on the motor should require a 1.4142135 (square root of 2) times increase in voltage, to cause the current to increase by the same percentage. If you run the motor unloaded, you can turn the voltage way down, to get the motor to draw the minimum current. (I have run a 7.5 horsepower, 4 pole three phase motor on as little as 12 watts). The power factor will remain as high as possible. If you cut the voltage back too much, the current will begin to increase again, and the motor will slow down. The power factor will begin to increase once again. It's a very fine line between optimum voltage for the load, and too low. The motor will quickly stall, if you cut the voltage even a small percentage below optimum for the load. As one of you has a hand on the brake, the other should have their hand on the variac (variable transformer). Watch the current, and chase it with increased voltage, as the load increases. Be careful! That motor looks like it can burn that brake band very quickly, if you get close to nameplate current and voltage, thus, horsepower.
Sir es practical book ki pdf milegi
