how you can select circuit breaker for 2000kva transformer?

Answer Posted / solver

gaurang you are right
also mukund is right

Dear ashish & sareer,

always remember that the LT side breaker of transformer
is only selected based on rated capacity of LT winding.
i.e. 2782 A in this case.
& no overloading is considered beyond capacity of
transformer winding.
besides that transformer is loaded to 80% of its capacity.
This makes the load current even lesser than the rated.


Hope you are satisfied by this answer
