The inventive glove provides a work glove that detects the presence of AC voltage without compromising its usability as a work glove. Embodiments of the inventive glove include monopole aerials extending into the fingers of the glove. A thin flexible dielectric layer sits between the aerials and inside of the glove, acting as an electrical barrier between the aerials and the user's hand. The aerials are connected to conventional voltage detector circuitry on a circuit board located on the back of the glove. The circuit board is grounded to the user's wrist, which enhances the circuitry's ability to detect the presence of nearby AC voltage at a safe distance.
