In my previous article, I have provided the different formula for calculating fault currents in different fault scenarios. We will put that into the application at this time.
A utility has given these values to our design team:
3-Phase Fault Current: 2424 A
Phase-ground Fault Current: 294 A
From the above values, whichever values your use, current or impedance, your calculation will provide the same result. To verify this,
Three Phase Fault:
Note: Since we are distant from the generator, .
