TESTER OF MULTIPLE-ELEMENT PASSIVE BIPOLES Russian patent published in 2010 - IPC G01R27/02 

FIELD: electricity.

SUBSTANCE: measurement of parametres of passive multiple-element bipoles is performed at influence of pulses of voltage varying as per the law of n degree of time on measuring transducer and at balancing of output voltage of measuring transducer and compensating signal synthesised from voltage pulses having the shape of degree functions of time with degree properties of n to 0. After transient process is completed, there set to zero are voltages on outputs of (n-1)-cascade differentiator connected to output of inverting summator, as well as at the output of the latter. As per the obtained amplitudes of the above pulses there calculated are conductivity parametres, and then - parametres of elements of a bipole.

EFFECT: enlarging functional capabilities, simplifying and standardising the measuring algorithm of parametres R-C, R-L and R-L-C of bipoles having various equivalent circuits.
