SUMMARY

The discussion revolves around solving transformer problems using the formulas (VH/VX) = (TH/TX) = (IX/IH) and I = kVA/V. The user is specifically addressing the relationship between voltages 2400 V (VH) and 480 V (VX) and is attempting to confirm the correctness of their calculations regarding ampere-turns. The conclusion drawn is that ampere-turns must be equal, which is a fundamental principle in transformer theory.

Homework Equations


I've used these formulas
(VH/VX) = (TH/TX) = (IX/IH)
for solving the turns although I'm not quite sure if 2400 V is the VH same as for 480 V

for solving the ampere-turns, I = kVA/V
where:
V= either the VH or VX
then multiplied the current I got to its voltage.

Now, I'm not quite sure if my solution or my way of solving is correct.

Can you please confirm if my solution is correct? Thanks!

I've found that the ampere turns must be equal. Although I'm still not sure if my solution is correct. :H
