Question at 4:59 I would think that because there is an impedance between Vbase2 and the primary side of the (20:1) transformer, what you would actually be stepping down here is (Vbase2 - Ibase2 x Zline). That is to say there is voltage drop that occurs across Zline to the primary side of the (20:1) step down transformer. Therefore Vbase3 = (Vbase2 - Ibase2 x Zline) / 20. Could you explain why this would not be the case? Thank you for this video, it is the best example I have been able to find explaining how the per unit method can be used to simplify a power system.
I thank your formula is correct. But you can't use it to reach V3,base, simply because you don't have the required impedance which is Z3,base, NOT Zline !!!
Nicely explained with practical example. Many others have tried theoretically which does not help some time in engineering. ;) You are the best. Keep it up.

Hi Tharindu, Thank you for contacting us on your query. In the video above, we have assumed the voltage drop due to resistance of the transmission line as negligible. The objective is to keep the per unit calculations simple and easy to comprehend. When we analyze complex transmission models at a professional level we do consider voltage drop due to resistance.

Wanted to ask, why is Z1, base= (Vbase)^2/Sbase and Z2, base = Vbase/Sbase. Please explase why V2, base is not squared in region 2 when find Zbase. Thank you..

Can i ask u guys something how we connected that parts so easily they have differnt bases they have only 1 same base and thats the s(power) all regions have absolutely different bases . U found pu units for only that region when u goto other rwgion base changes that means they not same per units i mean in one region 1 pu means 480 v in the other region 1 pu means 800 v look at that u add 1 to 1 and resolve is 2 pu but what is that means is that means 1600 v or 960 v which one is it how u can add them together so easily i think we should put them together in the 1 base so we can use them

@Knight_rider, Hi The calculated value of (4800V) is the new base value that would be used in region 2 and has nothing to do with the actual voltage drop. The base quantity remains the same throughout the entire network unless there is a transformer which would then split the network into different regions. When there is a transformer between 2 regions, the base quantities for Voltage, Current, Impedance changes (Base Quantity for Apparent Power remains unaffected by a change in voltage level). The base quantities are then computed using the turns ratio to obtain the base quantities that would be used in the next region. The base quantities are arbitrary values that are used to make computations of power systems easier. These base values are ultimately used in per unit calculations to make complex calculations easier. We have a video series on Per Unit Systems which explains in detail how these quantities are calculated.

Hello 👋, I'll like to know why V²/s was used in region one to find Zbase but V/S was used for other regions. Thanks in anticipation
Why you didn't include the Transformer in Region 1, i mean in the figure it looks like it's part of region 1?
Thanks
I wish the problem specified phasing. How do you know if it is single or three phase?
Shouldn't the voltage and power drop due to the impedances in region 2?
Salam, Example 2-3 part - d question where is video find the power lost in the transmission line ? Thanks
why are we neglecting voltage loss due to the resistance of the transmission lines?

Hi, Thank you for the lecture. I can't see where in the problem Zpu is given to be 1 for region-1. am i missing something?
never mind. got it. Vpu = 480/480 = 1
You got it!
