A 120 kVA transformer is to be parallelled to a 60 kVA transformer. Each transformer has rated voltages of 10kV-120V at 60Hz.

Tranformer 1, parameters referred to primary:
Rc=250k Ohm
Req=25 Ohm
Xm=45k Ohm
Xeq=150 Ohm

Tranformer 2, parameters referred to primary:
Rc=400k Ohm
Req=30 Ohm
Xm=90k Ohm
Xeq=300 Ohm
