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

FIELD: measurement equipment.

SUBSTANCE: in a bridge meter of parameters of n-element dipoles there is an additional resistor, an additional inductance coil, a build-up circuit is identified, quantity of such circuits is determined, and they are connected to each other. The total quantity of identical build-up circuits is equal to a quotient from division of n-2 into four (n-number of parameters in a dipole of the measurement object), if this quotient from division is an integer number. At the same time the last build-up circuit is complete, if the quotient from division contains integer and fractional parts, then the number of build-up circuits is equal to the integer part plus one, and the last build-up circuit is incomplete. The total quantity of elements in each of two identical dipoles in the second branch of the bridge is equal to the number of parameters n in the dipole of the measurement object, each subsequent build-up circuit is connected in parallel to the inductance coil of the previous build-up circuit.

EFFECT: expansion of functional capabilities of a meter, namely, a bridge meter makes it possible to determine parameters of R-C, R-L and R-L-C dipoles of measurement objects comprising five, six and more elements.
