FIELD: electric instruments. SUBSTANCE: method involves separate sampling of measured parameters according to switch turn number of grounded windings of voltage transformers with close inductive connection, when constant resistor is used in comparison arm and amplitude zero indicator is used in measuring arm of multiple-arm alternating current transformer bridge. Bridge balancing method involves balancing with respect to two different-type parameters at frequency, which is greater than given sampling frequency of measured parameters, and subsequent balancing operations with respect to sampling parameter of measured capacitance and sampling parameter of measured inductance at frequencies, which are less and greater than given frequency. EFFECT: increased precision and speed of parameters measurement using serial RLC circuit. 2 cl, 1 dwg
