We have a transformer with the following nameplate:

MVA: 21/28/34
Hi Voltage: 101000 X 50500
Low Voltage: 13090Y/7558
Impedance: 8.95% at 101000-13090 Volts and 21.0MVA

We have this transformer connected for 50500 volts. Will the impedance
be the same or different when connected at this lower voltage setting?

Thanks in advance!
