BRIDGE METER OF PARAMETERS OF DIPOLES Russian patent published in 2013 - IPC G01R17/10 

FIELD: measurement equipment.

SUBSTANCE: bridge meter of dipole parameters comprises serially connected generator of supply pulses, four-arm bridge circuit and zero indicator. The bridge comprises two parallel branches, the first of which comprises two serially connected resistors, the free output of one of them is connected to the first output of the supply pulse generator, the free output of the other one is grounded, the common output of these two resistors forms the first output of the four-arm bridge circuit outlet. The second branch of the four-arm bridge circuit comprises serially connected single resistor and complex dipole, the single resistor is connected to the first outlet of the supply pulse generator, the common output of the single resistor and the complex dipole forms the second output of the bridge circuit outlet. The complex dipole comprises two parallel connected branches, the first of the branches includes serially connected first resistor and inductance coil, the second resistor is connected to their common outlet, and the free output of the inductance coil is grounded. The second branch of the complex dipole includes two terminals for connection of the dipole of the measurement object, one of the terminals is grounded, the dipole of the measurement object comprises parallel connected first resistor and circuit from serially connected capacitor and second resistor, the common output of the first resistor and the capacitor is connected to the non-grounded terminal to connect the dipole of the measurement object, and the common output of two resistors - to the grounded terminal.

EFFECT: reduced error of measurement.
