Dear P.Kalivada 100KVA transformers total power (3 phase) is 100KUA one phase give 33KVA, Phase voltag is 11/1.732 = 6351 volt therefore current is 33000/6351=5.1 amp (at unit pf). You can see a name plate of 100KUA 11KV/433v tranrsformer it is written 5 amp as HT Current and 133 amp as LT side current you can verify any tranformer whose primary voltage is 11KV it's current is approximately to #/20 and secondary side of 433V it's current is approxhmately to # +#/3 ( # is how much KVA)
