Why Transformer in KVA?
Answer Posted / manikandan
Copper loss depands on current and Iron loss depands upon
the voltage.hence the total loss depands upon only VA. not
a phase angle between voltage and current . ie it is
independant of load power factor .Thats why rating of
transformer given in KVA and not in KW. It may be further
point out that temp. rise of the transformer is directly
proportional to apparent power which flow thought it.
