X/R ratio
X/R ratio
(OP)
I am trying to calculate the fault current on the low side of a transformer. The Transformer parameters are 69kV high side to 12.47kV low side, 40/55/67MVA, 11% impedance. With all of this said how does the X/R ratio figured into the equation?
And what is the "K" factor of a transformer?

RE: X/R ratio
Transformer X/R is not generally available directly, but can be computed from the transformer impedance and transformer losses, if known.
"K" factor is a measure of the transformer's ability to handle harmonic currents without overheating.
