A unit has a 2 identical 500 kVA transformers each with a no load loss of 840 W and full load copper loss of 5700 watt. The plant load is 400 kVA. Compare the transformer losses when single transformer is operation and when both transformers are in parallel operation.
Solution
transformer losses remain same whether they are connected single or in parallel
copper loss depend on current
iron loss depend on voltage
