Abstract
Expediency of the usage of resistors instead of the measures of capacitance for determination of adaptive error components of phase measurements and tangents of loss angles in selective meters of electrical quantity complex at the mains frequency is substantiated. At the same time the value range of input current strength is extended and the capability of error estimation for combination of voltage and current at the device's inputs appears. The admissible resistance range of resistors is indicated. Recommendations on application of AC bridge for experimental determination of tangents of resistor phase angles at the mains frequency are given. References 3, tables 2, figures 2.
