Short circuit fault mainly two types:
1.symmetrical fault2.unsymmetrical fault
symmetrical fault again two types:
1.between all the three phases and ground2.between all the three phases
unsymmetrical fault again four types:
1.between single phase and earth2.between phase and phase
3.between two phases and earth
4.betwee two phases and at the same time three may be a fault between third phase and earth
