Short Circuit Current Calculations - Eaton

ply the total motor current in amps by 4. Values of 4 to 6 are commonly accepted. Step 4. Calculate the "f" factor. Step 6. Calculate the available short circuit symmetrical RMS current at the point of fault. Add motor contribution, if applicable. Procedure for Second Transformer in System Step A. Calculate the "f" factor (IS.C. primaryknown) ................
