Earth Protection Coordination using ETAP II Earth Fault Relay Setting

Earth fault protection can be coordinated using ETAP software. Earth fault protection is set at 20%-30% of FLC (Full Load Current).
Earth fault protection can be provided by calculated fault current using the same phase CT current input (50N/51N) and by the measured fault current using neutral CT in transformer neutral (50G/51G).

Is there a way to calculate the earth fault current by manual calculation?
