Abstract
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.
