Latest Patents
Djokic holds a patent for a "Current-comparator-based four-terminal resistance bridge for power frequencies." This invention utilizes a current comparator technique to enhance the accuracy of four-terminal resistance measurements. The bridge operates effectively at power frequencies ranging from 50 Hz to 60 Hz. It employs active circuits to ensure equal voltage drops between the potential terminals of the resistances being compared. The device is capable of measuring resistances from 10 µΩ to 100 kµΩ. Furthermore, a cascading technique using two two-stage current transformers extends the ratio range to 100,000,000, with a maximum applied current of 10,000 A. The bridge boasts a measurement resolution of 0.1×10, and the total combined uncertainty (2σ) at power frequencies is estimated to be less than 5 µΩ/Ω.
