OVERHEAD-TYPE FAULT INDICATION POSITIONING TERMINAL AND METHOD FOR MEASURING VOLTAGE TO GROUND

WIPO Patent Application WO/2018/010369

A1

An overhead-type fault indication positioning terminal, comprising a capacitive sensor disposed in an overhead line electric field. The capacitive sensor is connected to a CPU of the fault indication positioning terminal via a conditioning circuit. Also disclosed is a method for measuring a voltage to ground for the fault indication positioning terminal. The real-time measurement of a voltage to ground voltage of an overhead line is realized, the change in the voltage to ground of the overhead line is captured, and a basis is provided for the determination of a line-to-ground fault.
