Fault level = Rated Voltage / system impedence (up to that
point)

transformer impedance can be calculated using the
following formula:

Z(transformer)=(Vsq*Z%)/(P*100)

where
Ztransformer is the source transformer impedance, in ohms;
P is the power of the transformer, in volt amperes;
Z% is the rated short-circuit impedance voltage of the
transformer, expressed as a percentage.
