ABSTRACT:
A single probe voltmeter for determining the voltage potential of high voltage transmission lines is disclosed. The voltmeter includes a capacitor having a spherical first plate connected to the transmission line through a rectifier network. The second plate of the capacitor is formed by the physical surroundings. An ammeter is connected across the rectifier network to provide an indication of the charging current for the spherical capacitor, which charging current is essentially a function of the transmission line voltage such that the ammeter provides an indication of the voltage potential on the transmission line.
