As i saw across the world, in the power system we can see single-phase or three- phase. In houses used single or three- phase only. In single phase, 2wires is there one is neutral that mean 0 voltage and another is 220v in single phase in that way moter is working. In some cases in industrial machinery 110v-2 wire is i saw that case the phase angle between the 2wires the one wire act like power and another is like neutral. Most i see if any mistake pls explain to my comment..❤⚡
With single phase, you have one sine wave. It produces 220 to 240 volts. The neutral is tapped in the center of the transformer, splitting the 220 into 2 110 lines. This is called split phase. There is no 2 phase. 3 phase has 3 sine waves and no neutral. If your utility supplies 3 phase then you need a transformer to get split phase.
Dear, I have 3-phase 3-treminal submersible water pump motor ,how can I connect in star-delta starting method b/c I have not auto-transformer starting panel board?rather it is satr-delta panel board;
So can I add a 3 phase motor to my clark pc60 phase converter which only has a 4 pin 16A plug (3 hot wires & earth) & connect thd pilot motor in star so a can gain a neutral output & use a 5 pin 32A plug ? Please help
Hello my friend, i have a doubt. I have a 3 phase induction motor with power 128KW, current 210A, pf 0.9, Voltage 440V, Frequency 60Hz, rpm 1180. Its a blower actually. Can I connect this in star if the motor specification is written delta. because if i connect in delta i guess starting current will be very high so im afraid it might burn the phases
Good knowledge sharing, keep it up
Best video sharing
Love your detailed explanations
Supar sweche sar, tq
Really clear and useful information, Thank You Sir.
One of the best experiences explain here
Thanks sir it is very clear and drawings, images well organized wi6 excellent explanation.
Well done
Well explained, that is why 🇮🇳 has good engineers.
Great explanation!
Amazingly clear & concise! Thank you!
This is understandable explanation
Thanks for the clear information. and the hypothetical examples helped also
excellent and to the point connection thanks
Super informative. Thank you.
My bro you deserve more than subscriber. Thanks a alot.
Correct explanation
Thank you sir am proud for you sir
thank you very much for the detailed information
Thanks
thak you very much!
❤thanks
Your way of explanation is outstanding 🎉
helpful video thanks to much.
Super bro… very useful
Thanks brother.
Hello Sir motor Delta connection can use with source 3phase 220v only or can use with 380v?
Great explanation thanks
Super 👍
Thank you!
Thanks អរគុណ❤
Most brilliant commercial electrician ever
Thanks a lot
Thanks 👍
Great lesson sir, please also make a video on parallel connection of alternators, the advantages and conditions necessary...
Question: If your house is getting 220V supply , then each power wire is 110V Single phase. Correct? The most you can run for motors is 220V 2 Phase ?
No

@@jeremycrisp4488 Thanks. Now it makes sense...

If you start in star and you stay in star will it damage the engine?
Can you start in star without a starter and not damage the engine?
❤❤
Thanks for your video how can i follow you

start connection: torque decrease 1/3 than delta connection; u=1/sqrt3 delta
There is no neutral in delta then where phase voltage and phase current come from

Wasn’t that last symbol delta and he said star?
it's torque,not touque
Really great information.
