METHOD FOR DETERMINATION OF TWO-TERMINAL NETWORK PARAMETERS Russian patent published in 2005 - IPC

FIELD: measuring the parameters of produced electric and radio articles (resistors, capacitors, inductances), and also the parameters of the transducers of physical processes (temperature, pressure and level of liquid and granular media) at industrial installations and transport vehicles.

SUBSTANCE: proposed method consists in shaping the sinusoidal voltage in a measurable two-terminal network at n frequencies, where n is the number of elements of the two-terminal network in its equivalent circuit. The values of complex currents through the two-terminal network and standard are measured at each of n frequencies. The two-terminal network parameters are determined by its equivalent circuit and by fixed results of measuring the complex currents through the two-terminal network and standard at each of n frequencies.

EFFECT: possibility of measuring the parameters of a two-terminal network, remote from measurement means; simplification of the design of measurement means when conserving their high metrological qualities owing to simplification of action sequence.
