DEVICE FOR MEASURING COMPONENTS OF TWO-TERMINAL CG-ELEMENTS Russian patent published in 2006 - IPC G01R27/02 

FIELD: engineering of measuring equipment for measuring capacities and conductivities of parallel two-terminal CG-elements.

SUBSTANCE: measuring device has harmonic voltage generator, connected to signaling input of attenuator, first and second phase rotators, first and second amplitude detectors and voltage indicator. Additionally measuring device has key, phase detector, set-point generator, phase indicator. Output of attenuator is connected to input of first amplitude detector and first input of phase detector directly, and to input of second amplitude detector, measured two-terminal element and second input of phase detector - through key and first or second phase rotator. Output of first amplitude detector is connected to voltage indicator, output of phase detector is connected to phase indicator, and output of second amplitude detector is connected to controlling input of attenuator through controlling device, supporting input of which is connected to output of set-point generator.

EFFECT: expanded spectrum of working frequencies and measured values.
