1. A transformer assembly, comprising:

  • a transformer having a primary winding with a primary connection and a secondary winding with a secondary connection;

    a first thermal sensor in thermal communication with the primary winding, the secondary winding, or combination thereof; and

    an airflow generator in signal communication with the first thermal sensor and arranged for fluid communication with the primary winding, the secondary winding, or combination thereof;

    wherein the airflow generator is responsive to the first thermal sensor to direct an airflow toward the primary winding, secondary winding, or combination thereof, in response to a winding temperature being in excess of a first temperature threshold.
