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.

Answer / reza

The trans act whit no happen.But we must use from reduced
load.

Answer / k.prakashchandra

Yes

Dear sir, In our plant have Station Transformer having capacity,i want to know, why LV side 40 - 40MVA is given? & how we can get 6.3 KV supply from tertiary(i.e. Open delta connection), Vector Group YNyn0 - yn0 +d MVA Rating 80MVA / 40 - 40MVA + 26.7MVA Voltage rating 420 (Tap range +6,to -10)81.25% /11.5KV - 11.5KV +6.3KV
