D86 series three-phase induction type meter was designed by the National Union of AC electrical energy meter, after nearly 20 years of production use and technical improvements, making the product more stable and reliable performance, for active or reactive power measurement and three-phase power system.

According to the user needs to provide bi-directional measurement, check, pulse output function of carrier communication products.

1, the electric meter in the products meet national standards GB/t 15283 0.5, 1 and 2 grade AC active energy in the form of the corresponding rating of all technical, reactive energy meter in accordance with the national standard GB/T15282 reactive energy in the form of the appropriate grade of all the technical requirements.
2, Watt-hour meter can be made by direct access and universal current transformer or multi-purpose voltage transformer both access.
3, start: energy meter at the reference voltage, reference frequency and COS=1 (var table SIN=1) condition, the load current does not exceed the starting current is shown in the table, meter dial is starting and continuing to move;
4, dive: when the current meter current circuits, voltage circuit, and when the voltage ratio of 80%~110%, Watt-hour meter dial to no more than one full turn;
5, dielectric properties: power meter can withstand shock wave is a standard 1.2/50 μ s wave and impact voltage of 6kV peak 10 times without damage. Power meter lines resistant to 2kV, frequency 45~65Hz sine waveform of AC voltage for 1-minute test.
