FIELD: measurement.
SUBSTANCE: invention relates to measurement equipment, namely to automated information measurement systems for commercial metering of electric energy. To determine complex resistances of consumers' branches and sections of four-wire main line in electric network, current measurements of current and voltage vectors at the beginning of line and each network subscriber in two different modes of operation of radioelectronic equipment, which arise as a result of changes in supply voltage and/or power consumed by subscribers. Calculation of complex resistances of consumers' branches and interpersonal sections of four-wire distribution network is carried out in head meter based on data of subscribers counters, measured under specified conditions.
EFFECT: technical result is expansion of automated measuring and information system for electric power fiscal metering functional capabilities in terms of current diagnostics and control of electric state of sections of distribution network lines 0_4 kV, as well as monitoring of commercial and technical power losses in it.
