The two power transformer 69/22.9kV and 230/69kV are both rated 60/80/100MVA designed for 60 Hz operation. However it will be tested on test facility were the available supply is only 50 Hz.
During short circuit test at the LV side the 60/80/100MVA rating will be tested for the lowest tap, nominal tap and highest tap (16R, N, 16L) each.
Question:
1. What must be current be to be injected on the HV side for each tap for each MVA rating at 60 Hz?
2. What are the equivalent values of these currents (60Hz) to 50 Hz? is there a formula for that? or standard calculation? (ie 60 to 50 Hz conversion or vice versa)
Thanks in advance
