  • WIRE VOLTAGE MEASUREMENT METHOD AND APPARATUS BASED ON ELECTRIC FIELD SENSOR
    Publication number: 20230324447
    Abstract: A wire voltage measurement method includes: acquiring a first corresponding relationship of an electric field intensity of a to-be-measured wire, a voltage of the to-be-measured wire, and a perpendicular distance between an electric field sensor and the to-be-measured wire; measuring at least four initial electric field intensities in an electric field sensitive direction through the at least four electric field sensors, and acquiring distances among the four electric field sensors along the straight line; calculating a second corresponding relationship of the voltage of the to-be-measured wire and an external interference electric field intensity in the electric field sensitive direction according to the four initial electric field intensities, the distances among the four electric field sensors along the straight line, the first corresponding relationship, and a spatial position relationship of the at least four electric field sensors; calculating the voltage of the to-be-measured wire according to the seco
