Autonomous Broadband Current Meter on a High-Voltage Electrode

The design of an autonomous noise-proof current meter on a high-voltage electrode is proposed, based on the use of an annular non-inductive shunt with its axially symmetrical connection to the input of the data acquisition module. The parameters of two design options are calculated: high-frequency, with a frequency band of 0–10 GHz, but with a lower limit of the measured current, and relatively low-frequency, with a band of 0–100 MHz, and a high limit of the measured current.
