DEVICE TO MEASURE CURRENT IN HIGH-VOLTAGE CIRCUIT WITH REMOTE DATA TRANSFER Russian patent published in 2013 - IPC G01R19/00 

FIELD: instrumentation.

SUBSTANCE: proposed device comprises power supply, current transducer composed of instrument shunt connected in parallel and having a direct contact with current lead whereat measurements are conducted, ADC and transmitter. Note here that transfer of data on measured current magnitude is performed by communication hardware via optical or radio communication channel. Note also that device proper is at high voltage potential in zone of no magnetic nor electric fields. In compliance with this intention, proposed device incorporates additional communication microcontroller including ADC, intermediate or base server, first and second low-frequency inductors, power supply filter and stabiliser, and tight shielding case. Note here that power supply is composed of feeding shunt connected in parallel to have direct contact with current lead whereat measurements are conducted. Note that said communication microcontroller can be incorporated with computer-based electric power control and accounting system at power generation and supply objects. Mind that device proper is arranged outside current lean and inside said shielding tight case.

EFFECT: higher reliability.
