Which outcome occurs when a transformer operating near saturation experiences a large DC current?

💡 Explanation

DC current biases the core into saturation, greatly increasing core losses via additional hysteresis because normal AC flux swings amplify; therefore, overheating results rather than efficiency gains because the core can't linearly support the flux.
