FIELD: computer engineering.
SUBSTANCE: invention relates to information-measurement and computer equipment and intended for calculation and indication of power loss averaged values, mains voltage and load current, and also can be used as recorder of these values for long period. Recorder comprises current sensor (CS) 1, mains voltage sensor (VS) 2, first 3 and second 4 input converters (IC), microcontroller (MC) 5, ambient temperature sensor 6 (ATS), conductor temperature sensor 7 (CTS), rectangular pulses generator 8 (RPG), third 9, first 10 and second 11 transceivers, digital indicator 12, read-only memory (ROM) 13, computer 14.
EFFECT: technical result is enabling possibility of continuous monitoring and recording of power loss, mains voltage and load current averaged values.
