Application

Three-phase watt-hour meter is that of inductance type, used for measuring three-phase AC activeor reactive energy of reference frequency 50Hz or 60Hz, DT862, DT864, DS862 and DS864 series are the three-phase active energy watt -hour meters, and DX862, DX864, DX865 and DX863 series are threephase reactiveenergy watt-hour meters.

Main Technical data

1. The active energy watt-hour meter conforms toall technical requirements stipulated in standardGB/T15283 Alternating Current Watt-hour Metersfor Active Energy (Classes 0.5, 1 and 2), and thereactive energy watt-hour meter conforms to alltechnical requirements stipulated in standardGB/T15282 Reactive Energy Watt-hour Meter.2. The watt-hour meter can be made into two kinds:direction connection type and the type of connectionthrough multi-purpose current transformer or multipurposevoltage transformer.3 Start: under reference voltage, reference frequencyand COS =1 (reactive energy watt-hour meter sin =1),when the load current can't exceed the starting currentin the table, the rotary disc of watt-hour meter canstart and rotate continuously.4. Creeping: w hen current circuit of watt-hour meterhas no current, and the voltage applied to voltage circuitis 80%~110% of reference value, the rotary disc ofwatt-hour meter rotates not more than 1 circle.5. Dielectr ic performance: when the watt-hour metercan with stan d impact waveform (standard waveform1.2/50 s)and impact voltage of 6kV peak value for10 times respectively, it won't be damaged. The circuitto-earth of watt-hour meter can withstand sine waveformof 2kV and 45~65Hz at AC voltage for 1min.
