Basic trafo amp-turn is I1N1=I2N2
CT ratio 100/1 so I1=100, I2=1
in case of bar primary
N1=1
SO N2= 100*1/1 = 100 turns
in case of wound primary
N2/N1=100/1=100
so in this case we must have information about N1 primary
turns to find out Secondary turns of CT N2

how much current capacity 250 amp. mccb please tell me about whats are the reasons to trip 2 or 3 times in a night. and what are the steps to short out this problem

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
