    Transformer Excitation

    That's what I was looking for regarding losses. The 13.8kV XFMR would be operated at or near 13.2kV.

    Transformer Excitation

    To clarify, the low side will be operated at 13.2 so to maintain 138 high side, I would need to tap at 144.9. There are obvious concerns if you overexcite a transformer, but I am curious as to any things to watch for under exciting it, other than the need to retap to maintain needed high side...

    Transformer Excitation

    I've got a question concerning XFMR ratios and excitation. Assume a Wye/Delta 138kV to 13.2kV GSU (138kV/13.2kV = 10.455 turns). Are there any issues with using a Wye/Delta 138kV to 13.8kV GSU, if I adjust the taps to closely match the 10.455 (set tap at 144,900kV to yield 144.9kV/13.8kV=10.5...
