Answer / athar abid
As we Know that
KVA = Sqrt 3 . Voltage(V) . Current(I)
Now for 400V (Phase-Phase) syayem
I = 500KVA/(1.732 * 400)
=500*1000/(1.732*400)
=721.7 Amps
There is no standard breaker available with this rating, so
take one step above rating i.e. 800Amps
Hope its clear.

Dear sir, I am working in wind mill division , pls explain Pls explain in details with formula My question is Wind speed 3.5 M/s Gen RPM is 1500 ( 25 K/w Production ) Wind speed 12 M/s Gen RPM is 1500 ( 220 K/w Production ) Why in 3.5 m/s generation was low , why in 12 m/s generation was high , Pls dont explain wind force or wind density , that one already i know For the above question RPM was same why the KW was different Answer : 1. Its depends on the density ( Force ) of the air Sir , Pls explain wit Formula sir
