Electrical Engineering: Ch 13: 3 Phase Circuit (22 of 53) Balanced Y-Delta Circuit: Ex 1

In this video I will find the phase current=?, line current=? of a balanced Y-delta circuit, the more common of the 3-phase, 3-wire circuit, given the phase voltage and the impedance (balanced load means all 3 impedance are the same). (Example 1)

You deserve a prize for your sharing of knowledge .thank you so much

[ayandamemela]

Thanks, i did not know that clicking to the link will help me, i got all lectures and the best part they are free, may God bless you.

[payerone]

This was an amazing video to re-educate myself on Y-delta circuits

[frankkwabenaaboagye]

the ICA; for abc, the c would be +120 added to the 13.43

[juansoto]

thank you for this series on 3 phase circuits! helped me so much, you're a beast boss

For the line current the angle is -30 so for Ib=the angle should be 90 and for Ic=it should be 120 degree

[Augustus]

at least share his content or simply watch the ad to support him.

[DulceSeeker]

because of what reason is difference between line and phase voltage 30degrees or which phenomena is responsible for that respectively?

[HARSHPIPAL]

Sir but phase voltage= line voltage for delta circuit, so why did you multiplied V by √3 in 1st step?

[MATHBOSS]

i thought phase voltage is the voltage across each load in other words V_AB, V_BC, V_AC ....now i am confused ... why is phase voltage V_an and V_AB line voltage

[sofiasmoshergonzalez]

Great video! really good practice w/ this example <3

[nellvincervantes]

And also the 120° for finding phase angles for phase currents of BC and CA?

[raghavrahul]

Bow ties are cool 😁
awesome stuff....this is pure gold.

[leonardopolanco]

Wouldnt it be easier to convert the delta impedance into wye impedance by dividing the load impedance by 3, then finding the line current by dividing phase voltage and load impedance in Wye form?

[hattrick]

For the current I_a wouldn't it divide into the two paths? If so is that accounted for when you utilise only the one path at root 3?

[suhailasaba]

Question: Why do you use the symbol of the voltage source as a circle with a plus and minus sign inside it ? Why don't we use the symbol of the AC voltage source sign which is a circle with a sin wave signal inside the circle ?

[happinessxelelo]

sir where does -30 degrees come from because this is the positive phase?

[عمرصبحيضيف]

can you tell me how many electrical power rise due to increase in number of phases ? or in another word, what is the relation between number of phases and power?

[kevonreid]

Isnt the phase and line voltage the same since we are working with a delta connection?

[ninjahunterx]

When we say 100 < 10 degrees. Is the 100, peak voltage or RMS value?
