Abstract
A system includes an electrical component, a MOV, a voltage sensor, and a circuit. The MOV is connected in parallel to the electrical component. The voltage sensor detects a voltage over the MOV and the electrical component. The circuit removes power in response to the voltage sensor detecting the voltage over the MOV and the electrical component being greater than a threshold voltage for a length of time greater than a threshold length of time. Removing power prevents the MOV from releasing one or more of smoke, smell, and sound. The MOV is thus not damaged as a result of a power surge. The system may be a power supply, or another type of electrical system. The electrical component may be a capacitor, or another type of electrical component.
