Transformer Fault Current Calculator With Calculation

A transformer’s nameplate details are 25 kVA, 440V secondary voltage, 5% of percentage impedance, calculate the short circuit fault current. I (fault) = 25 x 100 / (1.732 x 440 x 5) I (fault) = 0.66 kA. Notes: We have assumed the transformer is connected with the infinity bus to get the worse case fault level on the secondary side of the ...
