Short Circuit MVA values.
Short Circuit MVA values.
(OP)
When the taps of a transformer are raised (or lowered), does the available short circuit MVA at the transformer secondary raise (or lower) or stay the same as calculated at nominal tap settings?

RE: Short Circuit MVA values.
A couple test examples:
12 MVA 100-12.47 kV transformer:
105 kV tap - 8.84%
102.5 kV tap - 8.84%
100 kV tap - 8.87%
97.5 kV tap - 8.97%
95 kV tap - 9.12%
15 MVA 100-12.47 kV transformer:
105 kV tap - 9.18%
102.5 kV tap - 9.10%
100 kV tap - 9.08%
97.5 kV tap - 9.13%
95 kV tap - 9.22%
