How to decide the input and output circuit breaker for a 1600kva transformer.Is there any calculat..

1600kva transformer
p= root3*v*i*cospai 1600kva*1000=1600000
1600000/1.732*400*1=2309.46

total current= 2309.46
u can use transformer sec side acb 2500A
i think

The circuit breaker is selected based on following factors.

1. Voltage level
2. Fault current.
3. Type of Breaker.
4. Operating Time.
5. Number of operations.

How to decide the input and output circuit breaker for a 1600kva transformer.Is there any calculat..

it depends on the condition where transformer is put into
the service in the power systems because impedence vary
with these so fault current also varies

Answer / lokesh ranjith

Depend upon the contract demand the transformer will be
nstalled for full load ex: input will 850AVCB
output will be 2500A

the high voltage side the rating will be according to fault
level of the system and primary current. the secondary
rating also according to the full load current of the
transformer
