The strange thing is that I spent 4 hours on my homework and 2 semesters learning this, and I never understood it. Within 8 minutes I learned and understood everything. Thank you :)
Both equations Vline x I line x sqrt 3 and Vphase x Iphase x 3 provide the same answer. Line values are multiplied by sqrt 3 and phase values are multiplied by 3.
This is my second semester , so I’m still confused. I understand this perfectly how to do the math and everything. But in the real world, where do you use a delta-wye system?? In a house ? Building ? In a machine, like where ? 🧐
In Canada, our standard 3 phase transformers are Delta Primary, Wye Secondary. Your 3 phase loads can be connected as either a Wye connection or a Delta connection. For example, single phase loads that share a common neutral are connected as a Wye. Single phase, double pole circuits are connected as a Delta. Motors can be wound as a Wye or as a Delta depending on the characteristics you are looking for in the motor.
A better way we should be asking this question is, what causes me to wire primary a delta or wye. What causes me to wire secondary delta or wye. Primary is wired delta when the primary coil needs line to line voltage of circuit. If it needs line to neutral voltage wire it wye. Secondary is wired delta when the coil voltage of transformer is what the customer/ load required . 120/240 load and I have a transformer that on nameplate has 120/240 output then wire it delta. If I for example a customer/ load needs 277/480, then it would be wired in a wye. Reason is two different voltages with 1.732 difference between them. If the two different voltages are half and double each other (120/240) then wire it delta.
load that have neutral connection means it were star connection. while without neutral it will be delta. the real confusion come when you have a delta connected load and star connected load. to find out total from each phase.
It is impossible bro due to the loss of voltage, that's why our motors have only half eff or less. It is so rare to see more than 50% eff. Since we were talking motor it is also applied in the system
Fantastic! Thank goodness for youtube and people like you who took the time out to create these pieces of gold!

I just spent two three hours lectures confused beyond all belief trying to understand this. Thank you for clearing everything up for me.
So good to hear that the video helped out. All the best.
Pete
Perfect. thank you.
Thanks man! Superb!
awesome dude thank a lot
very well explained 👏
Bro can I please get a blank PDF of this worksheet? Or a link
Do you have one that shows Delta Feeding into Delta Load.? and one that is WYE feeding a Delta

Why single phase multiplication on delta va ??
Both equations Vline x I line x sqrt 3 and Vphase x Iphase x 3 provide the same answer. Line values are multiplied by sqrt 3 and phase values are multiplied by 3.
Beautiful
Hi I lke your video
In Wye case, is (W Total), actually (VA)? Is (W) = (VA*PF)
In this case there is only one 3 phase resistive load, so we don't have to calculate the VA
how can I find this kind of examples, from which source ? could you help me please

CAn you do with motor control circuit
What happens when the currents reach the N terminal of the wye connection?
The current at the Neutral node continues on to either of the the three phases, depending on the instantaneous voltage difference.
Thanks
For which job do you use this for?
Electrician, electrical technician, engineer
👌👌
has anyone found a 3 phase transformer with center tap neutral example
VA in = VA out
