Electrical Engineering: Ch 13: 3 Phase Circuit (34 of 53) Average Power per Phase?

In this video I will further explain the power in the 3-phase circuit in relation to what is the average power per phase. In the previous example we found the equation of the power as a function of phase voltage, phase current, and the cosine of the phase angle. Since phase current, phase current, and phase angle re constants then power=constant. Therefore for a single phase then Pp=(1/3)P.

Your formula in 3:13 should have the complex conjugate of the impedance in the denominator. S = V^2/Z*.

THANK YOU, VERY MUCH, FOR YOUR MOST EXCELLENT REVIEW OF THESE RELATIONSHIP FORMULAS!!!! MUCH

[kannanr]

Thank you so much sir. One doubt sir, (line voltage is =square root
of 3 × Vp ×angle 30°) the angle 30° is missing sir....

[udaykulkarni]

Nice explanation, Thank you very much

[Gokuwhaa]

thanks you sir, what is the diff between Pp and normal P

[saeedupdate]

I think you forgot to say about the differences in phase voltage and line voltage angle. phase voltage will lag line voltage by 30 degrees (or pi/6 radian).

[MATHBOSS]

in the rule S=Z times the magnitude of current ^2 you didnt mention of its the line current or the phase current which one is it?

[maheekhan]

Professor, in 3:10, it should be Z* than Z.

[ricogarcia]

Sir, I do recommend the proper usage of the terms complex power and apparent power.

Very good lecture Sir. Thanks 🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏

[roggameryt]

thank u sir for great explanation.❣❣❣❣

Sir but in Y delta 3phase circuit which u said its the common, both the linecurrent=√3Iphase and linevoltage=√3phase voltage then would the total powe of Y-Delta circuit be P=VLILcosΦ ?

[Zuwwar]

Hi. Shouldn't you have a Z* there?

[ΚλέαρχοςΤσίγκρος-ηκ]

why u say that n a delta connected load vl = vp we learned that in a y-delta connection is vl = sqrt3vp with phasor 30 and il = ipsqrt3phasor -30

[lalembahmanahsatyaalmahabb]

Why dont you multiple the line voltage with 3 for total power?

[jacksparrow]

Hello sir. Thank you very much for the explanation. I'm currently confusing wether we need different formula for delta or star connection. Regards
