ABSTRACT:
A preferred embodiment of a transformer includes a core, and a primary and a secondary winding positioned on the core so that the primary and secondary windings are inductively coupled when the primary winding is energized. The transformer also includes a sensor for measuring an operating parameter of the transformer, an audible signaling device, and an actuator for activating the audible signaling device when the operating parameter reaches a predetermined value.
