DTSF238/DSSF238 three phase electrical multi-rate watt-hour meter (kwh meter,energy meter,power meter)is a kind of new-style meter which is developed on the base of DDSF 238 single phase electrical type multi-rate watt-hour meter and widely heard power supply system experts and many users opinions and absorb domestic and overseas new techniques. It is a kind of potent measuring instrument for adjusting electric power load and reasonably prepare electric power source. It can user electric energy consumption by use-of time. Its technical performance are completely conform to the stipulated requirements of National Standard GB/T17215-2002Class 1 and class 2 static type alternating current active energy watt-hour meter and GB/T15284-2002Multi-rate ( time-of use) watt-hour meter.
       The 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.
