HIGH-VOLTAGE METER Russian patent published in 2020 - IPC G01R21/00 G01D4/00 

FIELD: measurement.

SUBSTANCE: proposed device relates to means of measuring electrical energy in industrial AC circuits. High-voltage metering device comprises measuring modules with optical outputs for data transmission, power sources, current circuit of each measuring module is connected to corresponding network wire, and voltage circuit is connected between this wire and network voltage measurement point, at that at least one of measuring modules additionally processes data received from other measuring modules. Each measurement module comprises transmitting and receiving optoelectronic modules, a combined optical cable, which includes optical fibres and current conductors, wherein current conductors are connected in voltage circuit, and each optical fibre is connected between transmitting and receiving modules of appropriate measuring modules and forms optical circuit by means of optical connectors arranged in zones of connection of voltage circuits.

EFFECT: technical result is increased speed of communication over a communication channel and high noise-immunity of transmitting data.
