Answer / k.prakashchandra

The VA per phase is (500/3 KVA) 166.67 x 1000 , phase
voltage is(433/1.732) 250 V.Then current in each phase is
166670/250= 666.68 A

Answer / shyam

The value 666.71 A gives the current rating i.e the maximum
current that the transformer secondary winding (each phase)
can withstand.The operating value may be less than or equal
to this RATING...

Answer / lalit pratap

Yes It's caring 666.71amps on each phase on secondary winding in transformer.
