Hi Cikizwa, I like your Lecture. Thanks

[@cikizwajames25]

Thank you. Am glad you enjoyed it and found it easy to follow.

Thanks for the video. In the Tutorial Q1, why Ia0 is equal to the current flowing back in the neutral? Shouldnt it be the current in the neutral divided by 3? since In = 3 Ia0

Thank you a lot mam

Thanks for the lecture so for unbalanced delta we use the same logic we used in Wye connected load to calculate the positive, negative, and zero sequence components for various voltages and currents.

[@cikizwajames25]

You got it.

[@Sizolwe]

Thanks. your help is highly appreciated

Nice class maim

L-n voltages are considered for 1st example

how do calculate the phasors, i see most of the time people use calculators, i love to find manually

[@cikizwajames25]

As long as you know the formula for positive phase sequence or negative phase sequence you can just add alpha to the angle you were given. Alpha is equivalent to 120 degrees while Alpha Squared is equivalent to 240 degrees. Adding up for your 0.1 and 2 is pretty hard without a calculator. If you do not have the calculator where you input angles, do it the long way. eg if your angle is 150 degrees, then you do a cosine of 150 + j(sine 150)
