How do you calculate 3 phase earth fault loop?

Answer:

You can't have a three phase earth fault, you can have a phase to phase or a phase to earth fault.

If you want the potential phase to earth fault current it will be your voltage times your impedance.

If you want the phase to phase potential fault current then you should just double the above result.

How does an earth or ground fault affect 3 phase motors?
Three phase Delta motors can continue to operate when one phase has an earth (ground) fault, when the motors are powered from an ungrounded Delta or Wye (star) service. This feature can be helpful in...
