Abstract:
A circuit protection device includes a trip mechanism and at least one capacitor configured to store electrical energy and to provide the electrical energy to the trip mechanism. The circuit protection device also includes a controller communicatively coupled to the at least one capacitor and configured to measure a charge property of the at least one capacitor, compare the measured charge property to a threshold, and output a signal indicative of the comparison.
