ABSTRACT:
A long-range wireless phasing voltmeter having a high impedance AC voltmeter in series between two high impedance probes. Shielding surrounds and electrically isolates the voltmeter and probes that communicate wirelessly via a pair of frequency translators, thus eliminating the cable customarily used to connect the probes and enabling measurements of the voltages, voltage differences, phases and phase difference between two conductor that may be miles apart. The signal transmitted from the first probe to the second may be analog or digital and is automatically compensated to correct the synchronization of the transmitted signal for the delay required to send it via the two translators.
