摘要： A wearable electric field detector configured to be worn by a wearer in an environment includes inner and outer housings which are movable relative to each other between a closed position and an open position. When in the closed position, a body of the inner housing is concealed within the outer housing, and when in the open position, the body is partially visible to visually indicate that the detector is open. The detector includes field detection circuitry which is configured to detect voltage in an electric field in the environment around the wearer. The circuitry is in communication with at least one of a speaker and a light source which are configured to be activated by the field detection circuitry.

摘要： A high voltage digital voltmeter and wireless phaser includes first and second voltmeters/phasers. Each voltmeter/phaser has a probe for accessing a point in a circuit, circuitry connected to the probe and including a microprocessor, and a ground reference associated with the circuitry. Each microprocessor is programmed to measure line-to-ground voltage of the respective voltmeter/phaser. This information is shared between the microprocessors and is used to determine voltage measurements and phase angle difference.
