Description
ã€Overview】
Three phase smart energy meter
adopts large scale integrated circuit, apply digital sampling
processing technology and SMT technology, the meter is designed and
manufactured according to industrial user’s actual consumption,
which reach international advanced level. Electric energy meter
consists of measurement unit, data processing unit and
telecommunication unit, which has the function of power metering,
information storage and processing, true time monitoring,
etc.
Three phase smart energy meter can accurately measure forward
direction, reverse and combined active power, four quadrant
reactive power, combined reactive power, combined reactive power,
and also can true time measure active power, reactive power,
voltage, current and frequency, and some other
parameters.
ã€Function
details】
* Electric energy meter has
built-in hardware clock that has temperature compensation function.
Its calendar, timing and leap year can change automatically, and
special tariff for festival and holiday.
* Gauge positive, reverse, combined active power total, sharp,
peak, flat and valley power, combined active power metering module
can setup arbitrarily according to active power combined way tagged
word.
* Storage maximum required quantity and occur time of active power
forward and reverse’s total, sharp, leap, flat and
valley
freeze at fixed time, instant freeze, convention freeze, daily
freeze, integral point freeze
* Real-time measurement monitor: record, display present electric
energy meter’s total phase/ split-phase voltage, current, power,
power factor and other operating parameters, when the power grid or
electric energy meter faces any unusual, the meter would record it
by the way of event.
* Load record content can be selected from the following 6
combinations of voltage, current, frequency; active, reactive
power; power factor; active, reactive total electric energy; four
quadrants reactive total electric energy; current required
quantity.
