For this question I am having some confusion for part 3).
I can't seem to get the same voltage regulation as him and I can't figure out what I'm doing wrong.
I've assumed the load to be on the leftmost portion of the HV side.
I've also assumed since we are at rated load that the current across the transformer is 1000V as per its rating.
Is there anything wrong with how I've drawn the circuit for the HV side? Are all the voltages in the correct places?
If so, I write a KVL,
\(-V_{load} -\vec{I_{2}}(R_{eq} + jX_{eq}) + 1000V = 0 \)
From here,
\(V_{load} = 1000 -\vec{I_{2}}(R_{eq} + jX_{eq})\)
This gives me,
\(V_{load} = 1027\)
which is different from his answer.
Note: His answer he uses different names for his voltages. It seems as though he assumes the 1000V is across the load. How does he know this? We've only been given rated current!
Is his answer incorrect? Or is mine?
If it's mine, what am I doing wrong? Is there something wrong with how I've drawn the HV side? Did I place the 1000V in the wrong spot?
I am so terribly confused, I just want to know what I'm mixing up!
Thanks again!
Tnk where are you!?!? I need to clear this up before my exam!
