power consumption,

DD862 type single-phase watt-hour meter, that is, inductance type single-phas e AC acti ve energy watt-hour meter, it is used for measuring active energy at single-phase AC power grid of 50Hz or 60Hz. It has many features such as original design, reasonable structure, high overload capability, lower power consumpt ion, long service life, good stability, convenient adjustment and maintenance, etc.

1. The watt-hour meter conforms to all technical requirements stipulated in national standard GB/T 15283 Alternating

Current Watt-hour Meters for Active Energy (Classes 0.5, 1 and 2), and total technical re quirements for single-ph ase

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 COS =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. Cre eping: 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 1.2/50 s 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.
