In any system there are phase and neutral, where phase is
live while neutral is refrence wire. And this refrence wire
can be used to make the path availiable for returning
current.While its not necessary that this neutral may be at
zero potential(in case of faults).
But the ground is refrence with zero potential, in our
systems to increase capacity and fault current protection
Neutral point is grounded, this aslo prevents shock,

a)In a 3-phase 4-wire circuit, a circuit breaker is selected to protect the circuit whose highest fault level is 6.6 MVA. Determine the required minimum breaking capacity in kA. (Note: Covert 3-phase power in terms of kA to find answer.) b)Using the below, determine the required minimum making capacity in kA as a “peak value”. Rate breaking capacity (Icn) ka: Icn<= 1.5 Factor = 1.41 1.5
