Three-phase Multi-tariff Watt-hour Meter
Description of Three-phase Multi-tariff Watt-hour Meter:
The three phase multi-tariff electronic Watt-hour meter is a kind of new-style meter which is developed on the base of single phase multi-tariff watt-hour meter. We widely heard opinions from power supply system experts and many users, and adopted domestic and overseas new techniques to develop it. It is a kind of potent measuring instrument for adjusting electric power load and reasonably prepare electric power source. This three phase multi-tariff watt-hour meter can user electric energy consumption by use-of-time. Its technical performances are completely conform to the stipulated requirements of National Standard GB/T17215-2002 Class 1 and class 2 static type alternating current active energy watt-hour meter and 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 rated frequency 50Hz or 60Hz three phase AC active energy electric power consumption and can realize many tariffs calculating cost and collecting transcription meter 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 emplaced spare 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 period of times.
6. May realize data display by turns.
7. May choose 485 interface and long-distance pulse interface to realize collecting transcription meter.
