Short circuit current on the load side of buck-boot transformer (autot
Short circuit current on the load side of buck-boot transformer (autot
(OP)
I need to calculate the SSC on the Load of an autotransformer.
Any help would be appreciated

Ohm's it not just a good idea, Its the law.






RE: Short circuit current on the load side of buck-boot transformer (autot
You need to have the following data:
Rated power of the transformer
Rated voltage of the windings
Impedance (Short circuit voltage)
With these values you may get a shortcircuit current value that will give you a "good reference" (infinite bus).
You typically determine the nominal current and divide it by the impedance (in per unit), this will be the shortcircuit current magnitude for a three phase fault.
