CAPACITANCE SENSOR (VERSIONS) Russian patent published in 2014 - IPC G01R15/16 

FIELD: measurement equipment.

SUBSTANCE: first object of the invention represents a capacitance sensor for measurement of an electric field generated by a conductor under voltage. The sensor comprises a screening element, having the first screened chamber with the first open end facing the conductor. At the same time the sensor of the electric field is located inside the first screened chamber, and a supply electrode has a distal area located inside the first screened chamber, and a proximal area connected to a conductor, installed as capable of submersion into the dielectric medium. The sensor of the electric field is installed towards the side of the distal area of the supply electrode and at the distance from the distal area with the possibility to measure electric field developed by the specified distal area, the electrode of supply stretches via the first open end, and the sensor of electric field is distanced along the axis from the distal area of the supply electrode. At the same time the area of the supply electrode has the shape of a solid funnel, the leg of which is directed towards the distal end. The second object of the invention is characterised by availability of an electrode having a proximal area connected with the conductor and arranged in the form of a disc.

EFFECT: improved reliability.
