APPLIANCE FOR CURRENT DENSITY VECTOR COMPONENTS MEASUREMENT IN CONDUCTING MEDIA Russian patent published in 2017 - IPC G01R19/08 G01R15/18 G01R1/00 G01V3/08 

FIELD: measuring equipment.

SUBSTANCE: invention could be used for electric current density vector components measurement in conducting media. The appliance for current density vector components measurement in conducting media is composed of at a minimum one current density transmitter 2, which is housed within the body 1, and of at a minimum one electronic module. The transmitter is composed of the current-conducting wire 3 with the mounted on it current transformer 4. The electronic module is made in the form of the connected in series conversion unit 5 and primary signal amplification, tunable analog filters unit 6, voltage-to-digit converter (VDC) unit 7 on the basis of the microcircuit chip of the sound VDC with the outlet digital signal of a USB format, signal translator and USB interface supply unit 8, which is designed as two transmitter cable ends-mounted receivers 9 and 10. The current density transmitter 2 outlet is linked to the conversion unit 5 inlet and primary signal amplification, the signal translator and USB interface supply unit 8 outlet in linked to the registering computer 11 USB inlet. The current-conducting wire 3 is made of the conductive material having the electroconductibility greater than 100 Sm/m. The current-conducting wire 3 can be made in the form of the cylinder or in the shape of, for example, square bar, whereupon, the current density vector component, which is parallel to the axis of cylinder or the axis of bar, is measured. The current-conducting wire 3 flat ends are flushed with the body 1 external face. The device is equipped with at a minimum three ring shaped vibration damping elements 12 that are fixedly attached to the current transformer 4 with gaps relative to each other suitable for the adherence to the body 1 and made of the vibration damping material. The device body 1 is made of the dielectric material. The current-conducting wire 3 and the current transformer 4 along with the vibration damping elements 12 are rigidly fixed to the body 1, and the vibration damping elements 12 are extended from the body 1 inner face. The current-conducting wire 3 is energetically decoupled from the current transformer 4, the electronic module and the vibration damping elements 12.

EFFECT: measurement accuracy and interference protection increase.
