BRIDGE MEASURING DEVICE OF PARAMETERS OF BIPOLES Russian patent published in 2015 - IPC G01R17/10 

FIELD: measurement equipment.

SUBSTANCE: bridge measuring device of parameters of bipoles includes an in-series connected generator of feed pulses with variation of voltage during their duration as per a law of power functions, a four-arm bridge circuit and a zero indicator. To the bridge circuit there introduced are three additional resistors, an additional capacitor, and an additional inductance coil and in-series connected is the first additional resistor, an additional capacitor, the second additional resistor and an additional inductance coil. A free terminal of the first additional resistor is connected to the second terminal of the bridge circuit output; a free terminal of the additional inductance coil is earthed; the third additional resistor is connected between the common terminal of the first resistor, the inductance coil and the capacitor and the common terminal of the first additional resistor and the additional capacitor. An unearthed terminal of the available second resistor is connected to the common terminal of the available first resistor, the inductance coil, the capacitor and the additional third resistor, and the free terminal of the capacitor is earthed.

EFFECT: enlarging functional capabilities.
