MULTIPLE-ARM ALTERNATING CURRENT TRANSFORMER BRIDGE FOR MEASURING PARAMETERS OF THREE-PIECE DIPOLES USING PARALLEL-SERIAL GLC CIRCUIT AND METHOD FOR ITS BALANCING USING THREE PARAMETERS Russian patent published in 2000 - IPC

Abstract RU 2149413 C1

FIELD: electrical instruments, in particular, alternating current bridge methods for measuring parameters of triode dipoles. SUBSTANCE: method involves separate counting of measured parameters according to number of switched coils in grounded windings of voltage transformers with close inductance connection. In addition, method for balancing with respect to two parameters of different types uses frequency, which is greater than sampling frequency of parameters to be measured. EFFECT: continuous measurement of resistance in comparison circuit and amplitude zero reader in measuring diagonal of multiple-arm transformer bridge, increased precision for measuring parameters of three-piece dipoles using parallel-serial GLC circuit, increased speed of measurement. 2 cl, 1 dwg
