ELECTRONIC CURRENT AND VOLTAGE SENSOR ON HIGH POTENTIAL Russian patent published in 2014 - IPC G01R19/25 

FIELD: electricity.

SUBSTANCE: invention refers to the field of electric measurement equipment and may be used to measure currents and voltages. An electronic current and voltage sensor on high potential comprises a metering module, a high-voltage current conductor connected to an analogue-digital converter. The supply inlet of the analogue-digital converter is connected with an accumulator by means of a power supply selection unit, and also with an optical source of power supply. The outlet of the voltage divider is connected to the inlet of the analogue-digital converter, the outlets of which are taken out from the metering module by means of optical channels. The voltage divider is fixed in a support insulator. In the metering module there are the following additional components: a voltage converter, connected to a low-voltage arm of the voltage divider. Optical channels are connected to a communication module, comprising a communication controller, a power supply unit, a pump module of a laser diode, an alarm unit. Also the device comprises an interface SPI.

EFFECT: increased stability of current and voltage measurement on high potential.
