FIELD: measurement technology; instrument engineering.
SUBSTANCE: commercial consumers' load is connected to power supply network through actuating user's devices. Any mentioned unit is subject to remote control through radio channel. Instant values of voltages and currents are measured. Effective values of voltage and consumed load current within one period are calculated on the base of measured values. Data is recorded into memory upon receiving command transmitted by radio channel from center. Simultaneously instant values of voltages and load currents are measured in all the points of connection of consumers to power network. Effective values of voltage and consumed current are calculated within one period taking measured values in to account. Measured values are memorized in memory of units. Measured values of voltage and load currents are read out, total resistances of users' loads are calculated on the base of measured values and phase voltages are calculated in all the points of connection of loads by using power network substitution circuit. Differences in calculated and measured values of voltages are calculated at any unit of network. Sites of non-controlled consumption of electric power are revealed from maximal values of difference between calculated and measured values of phase voltages and value of non-controlled consumed power.
EFFECT: widened functional abilities.
