PROCEDURE MEASURING COMPONENTS OF COMPLEX IMPEDANCE OF TWO-TERMINAL NETWORK AND VOLTAGE ACROSS IT Russian patent published in 2003 - IPC

FIELD: electric measurement technology. SUBSTANCE: procedure deals with measurement of active and reactive components of complex impedance of two-pole electric network and voltage across it without connection of measuring aids to one of its leads, specifically, parameters of insulation of high-voltage electric equipment right in process of its operation. Procedure consists in connection of resistor with variable resistance in series with measured two-terminal network, in measurement of voltage across it with three values of resistance and in computation of values of measured quantities by certain formula on basis of measurement results. EFFECT: provision for measurement of absolute values of components of complex impedance without use of bridge measurement network, for measurement of parameters of individual two-terminal network without employment of other two-terminal networks and for possibility of determination of voltage across measured two-terminal network. 2 dwg
