Electrical Engineering: Ch 13: 3 Phase Circuit (23 of 53) Balanced Y-Delta Circuit: Ex 2

[@yolokazizungu9074]

the correct answers for the line currents are as follows: Ia = 8.66 with a phase angle of -100 degrees Amperes ib = 8.66 with a phase angle of -220 degrees Amperes ic = 8.66 with a phase angle of -340 degrees Amperes

right

[@sanusanujan6920]

@@markfar4837 then why did he do like this? plz. make sure when you answering!!! @Michel van Biezen

[@trolee9987]

yup that's correct since line current lags phase current by 30 degrees.

[@Ser3naaaa]

Doesn't the line current lag the phase current by 30 degrees? Should you be subtracting 30 degrees from -70 so its -100?

[@romeissa5232]

U are right !!!

[@burakkarakus7681]

Yes it sould be. Just in the previous video he did it with the minus sign. Also I checked the textbook.

[@islamzerrougui7718]

i have the same remark here

[@backtonature1923]

so , what is the correct answer?

Prof Van Biesen is making sure everyone is paying attention. 😉

[@kannanr9016]

Line current is lags phase current by -30° but you wrote +30° sir.....

[@MichelvanBiezen]

You are correct it should be - 30 degrees

i am enlighthen now. thx for your hard work. hoping more videos to come from you

[@ceyk2023]

In the next video, you substract 30 degrees from the phase current to find the line current. So I am confused why here +30 and in the next same Y-Delta connection -30 degrees

[@davenandrew7292]

Sir line current lags phase current by 30 degrees. Why adding 30 degrees? Please clarify on that. Thanks.

[@MichelvanBiezen]

I believe that was a mistake. Look at the other comment below. Others have found it as well.

What is Ian current?

[@sohailjanjua123]

Hi Michel , Line current is lags phase current by -30 degrees and you wrote + 30 degrees why? Please explain me . Thanks

[@SAJ-wk6hz]

you are correct, it should be lagging (he should have minused 30 not add)

[@thefutureengineer6975]

The line current lags the phase current by 30 degrees
