I have always wondered about 'why only three phases' and now that you have given an excellent explanation, my questions have been answered. Thank you.
Glad it was helpful!! Do share the video !! ❤️
Do you realize how calming your voice is when you say “ watch the video”? When I hear you say it I know I am about to learn something great.
Previously we said that 3 phase give 1.5 times and single phase give Pm/2.....how we are saying that 3 phase gives 3 times more power
Actually we use a multiplier of the root(3) ≈ 1,73 times more power for the same voltage and current conditions, but anyways, a 6 phase system (I guess) would only give a multiplier of root(6) ≈ 2,45. Considering that we would need 6 lines in that case it would be beneficial to rather run 2 x 3 phases in parallel, thus doubling the lines carrying current capacity.
But still ceasing them compatible with existing infrastructure and not having to sets shifted at 60° angle😅
3 phase give 1.5 time the max power of single phase. And 3 times the average power of single phase 👍
Cool explanations Sir. I will take some time to look at some clips on working and coiling alternators. It will settle some other questions in the brain that I may not know how to put. Thank you a much.
When reversing the direction of motor's rotation we change just two phases, in case of six phases supply system the reversing will be complicated and time consuming.
I'm imagining a system where power is generated by a 6-phase turbine, but distributed by existing 3-phase utility lines; 3 phases go one direction on one set of lines, and 3 go the other direction on the other set of set of lines. Each of the 3 delivered phases would be 120 degrees out of phase, as they are currently. The only thing to change would be the turbines to generate the power, and slightly modifying the transmission lines to head in opposite directions as they leave the power plant. Would this work?
i am really great fan of your teaching and comand you have on electrical engineering .
Thanks 😊
A 6 phase system is just two 3 phase systems with 60 degree phase delay. You can try to pack them into a single 3 phase delivery system.
Also with double the wiring on the generator stator the resistance on the rotor is doubled. Energy doesn't come out of nowhere.
A 3 phase delivery system can be seen as three PAIRS of single phases with 120 degree delay each and cancelling out their loopback cable since it's always zero amps. Sounds like SWER (use earth as the loopback) but not even involving the earth at all. More phases will NOT reduce the number of cables per power thus meaningless.
If it is why dont we give 6ph transformers output to two 3phase transformers with balancing ,if it happens a generator station can send power to multyconsumers with lo cost
You can convert 6phase into dc to inverter
Or
convert 6phase into UHVDC line
I dont think the materials and size will double...because u use the same diameter circle and u just split the copper wires to 6 inductors...
As always, thank you for the explanation.
Glad it was helpful!! Do share the video ❤️❤️
Well, in theory you can run 2 three phase motors using 120º phases at the same time, phase A, C, and E to one and B, D and F to other. Both will run at max power, with "no change" in the consumer side. Apart from, more 3 wires, and 6 phase breakers.
Mechman 6 phase high current alternator have 12v 500amp dc and idlepro extreme alternator have 24v 600amp dc...so if car alternator can convert ac to dc 12v 500amp and 24v 600amp alternator maybe power generation plant can do they same...
Their alternator is 6phase hairpin double delta stator...if this technology will made it is posible to generate 2gigawatts of power per generating units
You're doing a great job sir🙏🙏
Thanks 😊
good Explanation and same way 6 phase is purely benefit the User it is difficult in power producer
Thank you !
respect to this guy for telling that if you in rush
this man should to give noble prize , if any shuch thing available in our electrical eng . field . unbelievable to so straight and simple explanation .
Thanks 😊 do share the video ✌🏻
six phase is possible in cheaper way through rectification like what china did..they bought siemens 1100kv transformer to transport 12GW of power over a 3000km then inverted to 3 phase.
Heard that 6 phase is used when you need a massive amounts of torque.
Long distance double-circuit 3-phase transmission lines can be converted in 6-phase lines using transformers at both ends. Operarional complexity and cost increments gets thus restricted to the zone between both conversion transformer banks. In this case 6-phase exceptional regions can coexist with the convetional 3-phase bulk system. This possibility is an alternative to HVDC for long distance transmission, in which the increased power rating can justifty the cost increment at the substations.

Please give the electrical guy group link❣️.
Your explanation is very excellent 😊 and these content was very important to engineering student.
Thanks 😊 Do share the video 👍🏻
@@GauravJ please give whatsapp group link ❣️
Can we use six phase generators and motors in EVs for better efficiency regarding range and range extender ability of the engine?.
I can be wrong, but with 3 phases we already have 6 poles in the motor. You can increase the number of poles rearanging the wirings, maybe more phases will give you better torque, but i don't think it will worth it.
@@NikolasOldSchool thanks bro
7ph (5ph, 11ph, 13ph, …) system is even better, making the otherwise simple calculations a cumbersome mess + heptagonal configuration of everything 😆 (5ph is another good choice).
PS Value added - heptagons cannot be constructed with a compass and straightedge 😆.
excuse me, you haven't mentioned the relation between number of phases and power
These models and sophistication are good to go to mars if there is chance...
Good
very well explained anna... iam studying 2nd pu and i found ur YT channel accidentally and it has helped me to understand basic concepts... TQ
Glad to know that ☺️ Do share and subscribe 🙂
First, I want thank you for all details
second, Why did you say we will not get double power of six phase?
It not clear for me the power curve declined.
Yeah, the theory says, if you have 12 phases, you cannot get double power delivered than the 6 phases.
great explanation ❤
Thanks 😊
Why would a consumer need a 6 phase motor? Wouldn’t consumers still be able to only connect to a 3 phase supply if they chose to?
They could. But, if they are still using 3 phase motor then, transporting 6 phase power would be of less use, isn't it? To get the benefit of 6 phase power, they need 6 phase machineries.
@@GauravJ not if the consumer run two identical motors.
Sir look good in beard
Why not only 2 phase ? Even 3 phase looks more complex. 2 phase give double the power but we can save on other equipment you mentioned.
Sir please tell me with a clean theoretical explanation sir..? With calculation..?.. So only engineers can success in interview...
with 6 phase can 3 phase for one remaining 3 phase can be used for distribution
You can power two separate three phase systems from one 6 phase generator for sure, but than you have to deal with load balance and the power factor of the two systems interacting with each other, the voltage will oscilate in on system based on the load of the other, will be a nightmare.
So, question for you, if a Home that gets 120/244 converted to a three phase system, first how would that be created. Second, is the electrical usage going to be less because it’s in three phase now versus single phase.? Greatly enjoy being educated by your videos.
I don't understand why it's saying it's possible but we have silly excuses. It would be better to say it's not possible or its something were doing. Not we can't afford it lol
Excellent vedio sir, 3 phase is more efficient in all aspects than 6 phase .Sir but can't we use 2 phase?
Bro Vedio is available in channel u can see it, because we have double the power of single phase but three phase will be three times more than single phase
@@260-pawankumar7 thank you bro but faults can be reduced if use 2 phase
Sir why do we need to buy a 6 phase motor when we give a normal motor we will get mechanical energy please say sir
The output torque of 3 or 6 phase motor is more than the 1-phase motor where we need more torque like lifts ,cranes we use 3-phase motors
@@Pavankumar-co9qv thanks bro
We can use more phases to generate and use powers locally as single phase..... not for transmitting long diatance....
Well, you cannot build a power plant near to a city or village to use that power locally . Power plant has be far away from the residential area or near to some source (coal, water). We’ll definitely need to transmit that power.
@@GauravJ I am saying in locally generated generators..... called gensets....
Yeah but those are the portable energy sources. Do you think we can manage to have a portable 6 phase generator? In my opinion, no. And also if we use only single phase power then, it will just act like single phase generator. There won’t be any benefits of having six phase generator anyways.
@@GauravJ I have one question related to transformers.... How the if the voltage is increaed current get decreased.... to transmit for long distance power is transmitted at higher voltage .... if voltage is increased its corresponding current also will increase.... How can we say High voltage low Current power is transmited.... it is my doubt...
@@GauravJ we can drive two individual three phase power devices separately by 6 phase locally generated power....
I was thinking the same question 🤣
Autorickshaw with 4 wheels would better, more safe my opinion
Yes, but then, we are making it costlier..
@@GauravJ safety first ;D
With three wheels, it is already safe and at lower cost. Isn’t it?
@@GauravJ yeah, and two wheels is better by lower cost
Intro music is a straight rip from idubbz content cop ( -- __ --- ), #1. Anyway after watching your video, you analogy makes no sense about 3 wheeled vehicles since 4 wheeled vehicles are the most common and by you analogy motorcycle's would be better than a 3 wheel. So let me break it down for you and anyone else reading this comment. 1 phase would = wheels and power = GVW. so yes the more wheels a vehicle has the more complex but the more it can carry., Basically it comes down to distance . #2. You didn't even talk about Application of more than 3 phases. Such as what solution would higher phases solve? without cost and complexity aside. hypo thecal scenario, is it better to use (2) 3 phase generators to get the same performance as a 6 phase? using your same analogy, Maybe instead of wheels, We can think of it like how many cylinders to an engine. A 4 cylinder is less complex than an 8 is but a 4 cylinder is more complex than a 2 cylinder motorcycle engine. You wouldn't use a motor cycle to pull 53 foot cargo box would you?
First comment 😁👍
totally zero info
Why not 360 phase with very large ground?
It looks very difficult (or impossible in my opinion). Because with 360 phases there won't be any phase difference between the phases.
@@GauravJ each phase would be one degree apart.
Yes, but still, it’s very less.
@@GauravJ could you explain the power doubling on 6phase but not 12phase? Say you rectified all legs then had a infinite farad capacitor bank,for a given time a higher phase generator with the same inductances and resistances will produce more energy than a lower phase but why? And just a side note would love to see a 360phase rectified dc on a oscilloscope
@@brettmoore3194 to make it simpler think we have 100V and by adding degree for eg degree A has 0-degree angle b has 20 degree and C has 40 degree and so on, we get 24v between A-B 48 between A-C 70 between A-D and so on and let the Z be ground,
if we connect any phase(that is from A to R) to ground we get 100V and that is not worth it
unlike 3 phase system where we connect RYB which are 120 degree apart so if u connect R with Y or R with B it will always give 440v so anymore phase would be of no use to transportation it might be used in electric cars for torque if u arange in right order for eg if u connect A with B u will get 24v C with D u will get 24v if u want to increase it connect A with C u will get 48 and if u connect B with D u get 48 volt and so on, u can use it for torque, regen brake etc.
