David,
Thank you for the reply. So do I have this right. The impedance of the transformer is irrelevant and if the fault current of 9000A is on the secondary of the transformer the current flowing at the same time as the fault on the primary would be 9000 divided by the turns ratio of...
I am trying to understand how to calculate the fault current that will flow on the primary of a transformer when the fault is on the secondary.
An example would be as follows.
When a transformer is rated, 1000 kVA, 5.75%Z, 13.2 kV-208/120V.
If there was a fault of approx 9000A on the...
