Abstract
A system and method are provided for a floating reference recloser voltage sensor that measures low energy analog voltage from a voltage divider connected to a high energy transmission line electrode. A floating reference cylindrical voltage screen is coaxially positioned between a high energy transmission line electrode and a cylindrical ground plate, and is positioned closer to the transmission line electrode. The floating reference recloser voltage sensor is filled with a solid dielectric material. A voltage divider network is formed when a voltmeter of a recloser controller is connected to the high-voltage electrode and the floating reference voltage screen, and connected in parallel with another divider network capacitance. The voltmeter reads a low energy voltage drop between the high energy transmission line electrode and the floating reference voltage screen. The recloser controller and the voltmeter are both disconnected from ground.
