Abstract

See full text

A method of determining a lifetime parameter of a capacitor in a failsafe device including measuring an amount of energy required to return the failsafe device to a failsafe position, measuring an effective capacitance of the capacitor, and comparing the amount of energy to the effective capacitance to determine the lifetime parameter of the capacitor.
