A phasing voltmeter having a dual input AC voltage measuring device in parallel with a series configuration of two high impedance high voltage resistors and two metering resistors. Shielding surrounds and isolates the voltmeter and is connected to the series configuration at a junction between the two metering resistors. The AC voltage measuring device measures the voltage across two voltage lines as well as the exact values of the stray AC capacitive charging currents associated with all high voltage sources. From these previously undesirable stray capacitive charging currents, a math processor in the voltmeter and in contact with two dual input measuring device receives input from between each resistor in the series, determines and displays the actual voltage across the conductors, its origin, the leading phase, lagging phase, phase sequence and phase rotation of the voltages on the AC conductors undergoing testing.
A voltmeter for indicating voltage and phase difference between two power lines, said voltmeter comprising:
