Two single phase transformers are connected in parallel with the following parameters.
Transformer A, rated at 60 kVA
Rc=250 k Ohm
Req=25 Ohm
Xm=45 k Ohm
Xeq=150 Ohm
Transformer B, rated at 30 kVA
Rc=400 k Ohm
Req=30 Ohm
Xm=90 k Ohm
Xeq=300 Ohm
What is the total input current and power factor when supplying a combined seconday load current of 250A at 0.85 PF lagging if the output terminal voltage is 125V?
