Main Technical data

1. The watt-hour meter conforms to all technical requirements stipulated in national standard GB/T17215.311-2008Alternating Current Watt-hour Meters for Active Energy (Classes 0.5, 1 and 2), and total technical requirements for single-phase watt-hour meters (class 2) stipulated in international standard IEC 521.

2. The watt-hour meter can be designed into two kinds: direct connection type and the type of connection through multi-purpose current transformer or multi-purpose voltage transformer.

3. According to users requirements, the special watt-hour meters can be designed, including the watt-hour meter that has different reference frequency, reference voltage, different current specifications, positive and negative accumulation and not-return function  

4. Start: under reference voltage, reference frequency and COSφ=1, when the load current can't exceed 0.5% of basic current, the rotor of watt-hour meter can start and rotate continuously.

5. 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.

6. Power consumption: under the reference voltage, reference temperature and reference frequency, the active energy consumption of watt-hour meter voltage circuit can't exceed 2W. 

7. Dielectric performance: when the watt-hour meter can withstand impact waveform (standard 1.2/50μs waveform) and impact voltage of 6Kv peak value for 10 times respectively, it won't be damaged. Thecircuit-to-earth of watt-hour meter can withstand sine waveform of 2kVand 45~65Hz at AC voltage for 1min.
