Three Phase Watt-hour Meter/ Three- Phase Watt Meter/ Phase Watthour Meter DT862
Key Features:
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.
1. The active energy watt-hour meter conforms to all technical requirements stipulated in standardGB/T15283 Alternating Current Watt-hour Meters for Active Energy (Classes 0.5, 1 and 2), and thereactive energy watt-hour meter conforms to all technical 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 connection through multi-purpose current transformer or multipurpose voltage transformer.3 Start: under reference voltage, reference frequency and COS =1 (reactive energy watt-hour meter sin =1), when the load current can't exceed the starting current in the table, the rotary disc of watt-hour meter can start and rotate continuously.4. Creeping: w hen current circuit of watt-hour meter has no current, and the voltage applied to voltage circuit is 80%~110% of reference value, the rotary disc of watt-hour meter rotates not more than 1 circle.5. Dielectr ic performance: when the watt-hour meter can with stan d impact waveform (standard waveform 1.2/50 s)and impact voltage of 6kV peak value for 10 times respectively, it won't be damaged. The circuitto-earth of watt-hour meter can withstand sine waveform of 2kV and 45~65Hz at AC volt.
