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

FIELD: measurement equipment.

SUBSTANCE: bridge metre comprises serially connected generator of feed signal, a bridge circuit and a zero indicator. The generator contains shapers of rectangular, linearly changing, square pulses, a switchboard, a synchroniser, a power amplifier. The common bus of the pulse generator is connected to earth, and its first outlet is connected to the inlet of the electric bridge, the first of two branches of which is formed by a capacitor of a ratio arm, with one outlet connected to the inlet of the bridge, and a complex electric circuit. The second branch of the bridge is connected in parallel to its first branch and comprises serially connected capacitor of the second ratio arm and two terminals for connection of a measurement object. The common outlet of the capacitor of the ratio arm and the first capacitor form the first outlet of the bridge output. The common outlet of the capacitor of the second ratio arm and the terminal form the second outlet of the bridge output. Also the device comprises n-2 increment circuits, starting from n, equal to four, n - number of elements in a dipole. The last increment circuit is incomplete and comprises three elements - a resistor and two capacitors. Two outputs of the bridge outlet are connected to the differential inlet of the zero indicator, to the synchronisation inlet - the second outlet of the pulse generator, the common bus of the zero indicator is grounded.

EFFECT: expansion of functional capabilities.
