I am working on a practical transformer question as seen below. My thought process to solve this question was:
- 1) Calculate the total current supplied by dividing the apparent power by the voltage.
- 2) Find the current in the excitation branch and subtract it from the total current supplied.
- 3) Use this value to multiply the series impedance to find the voltage drop across it.
- 4) subtract this value from the input voltage and use this value with the turns ratio to find the output voltage of the transformer.
however there seems to be missing information as I cannot move forward with step 2. How do I find the excitation current without the reactive power? There is another question in my assignment with the same information supplied so what am I missing here? Thank you.
