Abstract
A method and apparatus for monitoring the integrity of a voltage regulating device. The voltage regulating device is coupled to a line receiving alternative current power. During normal operation of the voltage regulating device, the method and apparatus includes the use at least one capacitor that is either being charged or discharged on a repetitive basis. The voltage of the capacitor is assessed to determine whether the capacitor is charging or discharging and, thus, whether the voltage regulating device has failed.
