Three phase Electronic Multifunction Programmable Watt-hour Meter
Three phase Electronic Multifunction Programmable watt-hour meter is a hi-tech intelligent energy-measuring instrument composed of analog-to-digital converter A/D, calendar clock, special microprocessor CPU, liquid crystal display LCD and switching power supply and so on. This meter can measure import/export active/reactive energy, maximum demand, power, voltage, current, and perform data processing with reference to relative tariff.
Measuring import and export active energy in each time interval, measuring lagging and leading reactive energy, four quadrant reactive energy in each time interval, Output ports of photoelectric coupling for active, reactive, and clock impulse independently.
