say a transformer is designed for 33/11kv step down with ratio 0.33 for load 1

say a transformer is designed for 33/11kv step down with
ratio 0.33 for load 1 mva. if am giving 11kv as a input
that same transformer what will happen to its o/p voltage.
and whether it can be operated for 500kva

Answer / ankamsreekar

the current rating on 33kv side with full load is 30.30 in
case of 1ph transformer. if we apply 11kv to 33kv side the
transformer rating will be 333.33 KVA insted of 1MVA.the
voltage will be 3.66kv.

Answer / k.prakashchandra

The iron losses are reduced to nearly 33 %.As the tr
capacity is based on 'cooling vs heat generated',the
capacity can be higher than 333.33 KVA.

1 Answers KPTCL, NHPC,

In power generator sets, when they are coverted from 50hz to 60hz, the kva rating after conversion increases. For example, the manufacturer of a perkins 200kva @ 50Hz generator set has mentioned it to become 220kva after converstion to 60hz. What is the relation between the frequency & the KVA rating. Any formula please.
