@PRC, I am very amazed by Your post and answers. That is the reason I join in this forum actually. How I can ask questions to you directly? Please let me know.
Thank you.
@argotier @prc, thank you for Your kindly reply. Yes, I have checked With ABB, prc is right, they are measured at the max, rated and min taps.
According to za=0 (ideally), then Zb can be derived from 13.7% between windings 1-2 37.5MVA 110V/11kV and the same as Zc. 14.5% (1-2&3), 75MVA...
Hi argotier, thank you so much for Your reply. The way you read it also makes sense. But it seems still difficult to convert into a equivelent Circuit With Three windings. I have understood it in this way: Take the 15%-14.5%-14% as already calculated value Zp Zs1 Zs2 seperately, and derived the...
Hi, can you help me to read the data of the short circuit impedance of an ABB Three winding transformer. I have to put the values in to a equivelant Circuit (75MVA, 110/11kV).
Thank you
