Main Technical data

1 . all technical requirements stipulated in standard GB/T 15283 Alternating Current Watt-hour Metersfor Active Energy(C lassed 0.5, 1 and 2), and the reactive energy watt-hour meter conforms to all technical requirements stipulated in standard GB/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 COAΦ=1(reactive energy watt-hour meter sinΦ =1). When the load current cant exceed the starting current in the table,the rotary disc of watt-hour meter can start and rotate continuously.

4 . Creeping: when 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 . Dielectric performance: when the watt-hour meter can with stand impact waeform(standard waveform 1.2/50 μ s)and impact voltage of 6kV peak value for 10 times respectively, it wont be damaged.The circuit­to-earth of watt-hour meter can withstand sine waveform of 2kV and 45~65HZ at AC voltage for 1min.
