METRE OF DIPOLE PARAMETERS Russian patent published in 2014 - IPC G01R17/10 

FIELD: measurement equipment.

SUBSTANCE: bridge metre of dipole parameters comprises serially connected pulse generator, a metering circuit, an analogue summator and a zero indicator. The bridge metre comprises the first line of communication for an information signal, the second line of communication for supply pulses, an additional resistor, an operational amplifier, a non-inverting voltage repeater and an analogue summator. At the same time the first outlet of the signal wire of the first line of communication is connected with the inverting inlet of the operational amplifier, the second outlet of the signal wire is connected to the common outlet of the first and second resistors of the first branch of the metering circuit, the first outlet of the signal wire of the second line of communication is connected to the first outlet of the pulse generator, the second outlet of this signal wire is connected to the common outlet of the first resistor and capacitor of the first branch of the metering circuit, the second resistor of the first branch of the metering circuit is connected between the inverting inlet and outlet of the operational amplifier, the additional resistor is connected between the non-inverting inlet of the operational amplifier and "earth", the inlet of the non-inverting voltage repeater is connected with the common outlet of the first and second resistors of the second branch of the metering circuit, two inlets of the analogue summator are connected to the outlet of the operational amplifier and to the outlet of the non-inverting voltage repeater, the outlet of the analogue summator is connected to the inlet of the zero indicator.

EFFECT: higher accuracy of measurements.
