Answer / Anurag Khare

To calculate the Earth Fault Current, you can use the Blondel's Formula. However, it requires the system impedance (Zs) which includes resistance (R) and reactance (X). For a synchronous generator, these values depend on the generator's parameters such as voltage, frequency, RPM, and power factor (PF). Unfortunately, without specific generator parameters like stator resistance, synchronous reactance, etc., it is not possible to calculate the exact earth fault current.
