Abstract:
1. A device for measuring a voltage of an electric power line conductor of a power system comprising: a first electrically conductive housing configured to be installed on a first power line conductor; a first virtual grounding member configured to electrically ground a first housing to a first power line conductor voltage; a first measuring resistor electrically connected between the first virtual grounding member and an electrically isolated lead wire, the electrically isolated lead wire electrically connected to a first voltage dropping device, the first voltage dropping device configured to be electrically connected to a second power line conductor; and a sensor electronics module configured to measure a voltage drop across the first measuring resistor, the voltage drop being directly proportional to the voltage between the first power line conductor and the second power line conductor.
