What Is an AC Voltage Detector?
AC voltage detectors are devices used to confirm power outages in AC circuits before electrical work.
Essential for safety, they indicate the presence of electrical current through sound or light. These detectors vary by current type and are tailored for high voltage, low voltage, AC, or DC circuits. Modern electronic types are commonly used, offering non-contact voltage detection and a high level of safety.
Foil-type and neon-type detectors are used for educational and experimental purposes, but electronic types have become more prevalent in general use.
