Abstract :
Solution dedicated to measurement of small DC-bias current, being a part of large AC current in power grids, will be discussed in this paper. Ratio of AC/DC currents reaches 15000:1 or more. Such large ratio represents significant challenge in terms of accurate measurement of the DC current in the power grids.
