1.The active power KWH meter of these series products fit the standard of GB/T15283-1994<<0.5,land 2 class AC active power KWH meter>> all kinds of requirement,reactive power KWH meters fit the country standard of GB/T15822-1994<<reactive power KWH meter>> all kinds of techniacal requirements.
2.Electric energy meter can be made connection directly and through meter use current transformer or meter voltage transformer of connection two ways.
3.Starting:the electric energy meter’s dial can start and move around continuous when the reference voltage,reference frequency and cosΦ=1，load current is not more than KWH meter’s starting current.
4.Creeping:when the electric energy meter has no current,the voltage that added voltage wire is the reference voltage 80%-110%,the meter’s dial can’t move one around.
5.Current medium performance:the electric energy meter can be worked very well it through lashing wave shape is the standard 1.2/50 wavefrom,the crest value is 6Kv lashing voltage.The meter’s wire line can be tested for 1minute when the earh voltage is 2Kv,frequency is 45-65Hz actually sine waveform AC voltage.

Main feature：
|
| Three phase four wire electric energy meter is a kind of response KWH meter,it is used in measuring the energy of the reference frequency is 50HZ three phase AC active power and reactive power.DT862,DT864,DS862,DS864 are three phase active power electric meter,DX862,DX864,DX865,DX863 are three phase reactive power meter. |
