ABSTRACT:
A transformer comprising a primary winding and a secondary winding also includes a capacitor connected across at least a portion of the secondary winding within a housing of the transformer so that magnetically coupled voltage transients are filtered to prevent such transients from damaging a load connected to the secondary winding. An electrostatic shield is also included in the transformer to shield against capacitively coupled voltage transients. The capacitor also improves the power factor.
