Product Description

Three phase smart energy meter

【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.

【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.
