BRIDGE METER OF PARAMETERS OF N-ELEMENT DIPOLES Russian patent published in 2015 - IPC G01R17/00 

FIELD: measurement equipment.

SUBSTANCE: invention relates to the field of metrology. A meter comprises a pulse generator, a bridge circuit, a zero indicator. The bridge circuit comprises two branches. The first branch comprises terminals and a single resistor. The second branch comprises two serially connected dipoles. The outputs of the bridge circuit are connected to the input of the zero indicator. The second multi-element dipole of the second branch of the bridge comprises serially connected the first resistor and the first inductance coil, to their common output the second resistor is connected, also an additional inductance coil is introduced, which is connected between the free outputs of the resistor and earth. The circuit from the serially connected resistor and the inductance coil represents an increment circuit, quantity of such additional circuits is equal to $$\left[\frac{n}{2}-2\right]$$ at even number of elements n in a dipole of a measurement object, starting from the first circuit of increment, in this case the last R-L circuit of increment is complete, at odd number of elements n the quantity of additional circuits of increment is equal to $$\left[\frac{n+1}{2}-2\right],$$ also starting from the third circuit of increment, in this case the last circuit of increment is incomplete.

EFFECT: expansion of functional capabilities.
