FIELD: measurement equipment.
SUBSTANCE: group of proposed inventions relates to the field of information-measurement and calculation equipment, is designed for detection and indication of power losses averaged at a 1-minute interval. The first version of metre realisation includes a current sensor (CS), a square-ware generator, a multiplication unit, the first and second aperiodic links, the first and second sources of reference voltage, a summator, an environment temperature sensor (ETS), a point indicator, an electric equipment temperature sensor (EETS), an inverter, a switch; 2) the second version of metre realisation comprises a CS, a microcontroller, a register, a digital indicator, an ETS, an EETS, a generator of rectangular pulses, a transceiver, a computer.
EFFECT: increased accuracy and expansion of functional capabilities of a device.
