Description of Three-phase Multi-tariff Watt-hourMeter:
The three phase multi-tariff electronic Watt-hour meter is a kind of new-stylemeter which is developed on the base of single phase multi-tariff watt-hourmeter. We widely heard opinions from power supply system experts and manyusers, and adopted domestic and overseas new techniques to develop it. It is akind of potent measuring instrument for adjusting electric power load and reasonablyprepare electric power source. This three phase multi-tariff watt-hour metercan user electric energy consumption by use-of-time. Its technical performancesare completely conform to the stipulated requirements of National StandardGB/T17215-2002 Class 1 and class 2 static type alternating current activeenergy watt-hour meterand GB/T15284-2002 Multi-rate (time-of-use) watt-hour meter .

Application of Three-phase Multi-tariff Watt-hour Meter:
The three phase multi-tariff watt-hour meter is used for measuring ratedfrequency 50Hz or 60Hz three phase AC active energy electric power consumptionand can realize many tariffs calculating cost and collecting transcriptionmeter functions.

Structure and Features of Three-phase Multi-tariff Watt-hour Meter:
1.Palm type computer, infrared remote controller programming setup,transcription meter, distinguished by code.
2. The message is preserved forever if power is interrupted, inner emplacedspare batteries which are free of maintenance.
3. Module type switch and power, wide voltage range.
4. Can connect with computer, realize data copy and printing.
5. Have three tariffs, four time zones, four daily periodof times.
6. May realize data display by turns.
7. May choose 485 interface and long-distance pulse interface to realizecollecting transcription meter.
