ABSTRACT:
Dielectric absorption in a capacitor is detected by making a first measurement of the capacitance of the capacitor, then charging the capacitor to its rated voltage, then discharging the capacitor, and then promptly making a second measurement of the capacitance of the capacitor. If the second measurement indicates a capacitance value less than that indicated by the first measurement, the capacitor exhibits dielectric absorption.
