Typical X/R ratio
Typical X/R ratio
(OP)
I try to simulate a small industrial network using ELPEK software. For the source I have value of short circuit current. But for defining a feeder internal R and X are required and I haven't r/x ratio. I am looking for advice regarding typical values. I know they will vary, but I should start from somewhere.
This problem appears every time I have to simulate some network. Usually the only information available from the customer is short circuit power or current.

It may be like this in theory and practice, but in real life it is completely different.

RE: Typical X/R ratio
It's very variable as you saied.
I have some data, maybe it's help.

Source is 110/6,3 kV, 125 MVA power transformer, supplied through very short 110 kV line from a big system substation 400/110 kV.
