Can anyone give me an idea on how to calculate voltage drop through a transformer due to load?
Our system is 12470/7200 primary. For example I want to calculate the voltage drop through a 25 kVA 120/240 padmount transformer with a 4kVA load. The %Z on the nameplate is 1.9 and the R/X ratio is 0.9. I assumed a power factor of 90%. My calculations don't seem to come out right.
Thanks.
