A special electronic system under the influence of current flow
and applied voltage in each phase generates pulses in propor-
tion to the electricity consumed in this phase.
Phase energy consumption is indicated by flashing the corre-
sponding LED (L1, L2, L3). The sum of the three phases of pulses
indicated by a flashing LED is converted to energy taken in the
entire three-phase system, and its value is determined by the
segment LCD display.
The values of primary currents Ip of the transformers that can
be used are stored in the memory of the meter. The selection of
appropriate value, which corresponds to the values of the con-
nected transformers results in automatic setting of appropriate
coefficient, according to which the actual value of consumed
electric energy of the system is calculated. This value is indica-
ted on the LCD in a format that depends on the transformer
selected.
Values of Ip currents of transformers inscribed in memory of the
indicator: 5, 20, 30, 40, 50, 60, 75, 80, 100, 120, 125, 150, 200,
250, 300, 400, 500, 600, 750, 800, 1000, 1200, 1250, 1500, 2000,
2500, 3000, 4000, 5000, 6000.
