Three-phase
Multi-tariff
Electricity meter SET-4TM. 02. 2
FORWARD AND REVERSE DIRECTION
CONNECTED DIRECTLY OR VIA TRANSFORMER
Used for registration of active and reactive power in three-phase three-and four-wire 50Hz AC circuits. The meters provide measurement of full instantaneous power by each circuit phase as well as total, measurement of phase voltage, current, cos, waveform distortion factor of phase voltage wave in each phase. Technical and commercial registration of electric power, power flows in power systems at industrial enterprises. Registration of inter-system flows.
Can be used either independently or as part of automated electric power registration and control system.
O The meter allows viewing at the indicator:
- Active, reactive and full instantaneous power depending on voltage and current gain (integration period is 1 sec. ) per each phase separately as well as total of three phases, indicating quadrant which holds the full power vector.
- Power coefficient per each phase and total coefficient of three-phases
- Circuit frequency
- Current time and date
- Temperature inside the meter
- Phase voltage and current per each phase
O Recording and displaying active and reactive energy in forward and reverse direction per 8 tariffs in 12 tariff periods:
- Total since zero reset
- For current and previous year
- For current 11 months
- For current and previous 24 hours
O Measurement and storage of average active and reactive wattage of forward and reverse direction for making load graphs with integration time of 1 to 30 minutes.
