Description:General The DD862 single phase meter is designed to meet the latest IEC 60521. With accuracy of class 2, it measures active energy in single-phase two-wire or three-wire alternating power grids. Connection is direct or by instrument transformers. It is a reliable long service life meter. The average service life (MTTF) is 15 years and the maximal overload capacity is 667% Ib. The specifications of the meter can be tailored to customer requirements. Construction 1. Meter case: two types of the cases are available 2. Terminal block: the terminal block is molded of bakelite 3. Driving element: the driving element consists of a voltage element and a current element, both of which are fixed on the steel frame of fine magnetic conductivity; it has a load curve compensation device, low load and inductive load adjustment mechanisms 4. Rotor: the worm is an un-detachable part of the rotor shaft so that the mesh between the worm and shaft is improved; both ends of the shaft are embedded with graphite bearing to ensure the long service life of the meter 5. Braking element: the magnet is made of AlNiCo5 alloy and designed as U-shaped so that the effect of short time over currents upon the magnet is negligible 6. Frame: the frame is made of high-quality steel; its surface is treated by negative electrophoresis to achieve excellent corrosion-proof 7. Register: the register adopts heat- and abrasion-proof plastic gears and bearings; no lubrication of bearings is needed during the service life Technical data 1. Applicable standard: IEC60521 3. Accuracy class 2 (according to IEC60521) 4. Average service life (MTTF) 15 years 5. Basic current (maximum current) (A): 1.5(6), 3(6), 5(20),10(20), 20(40), 10(60), 15(60), 30(60), 20(80) (special currency as required) 7. Rating current of transformer in 5A direct connection 8. Reference voltage (Un): 110V, 120V, 220V, 230V, 240V 9. Reference frequency (fn): 50Hz, 60Hz 10. Power losses in voltage circuit at 50Hz Un 1.0 W/5 VA 11. Power losses incurrent circuit at 50Hz Un Ib<0.6 VA 12. Non-running with no-load 0.8~1.1Un 13. Staring current: 0.5% Ib 14. Mean temperature coefficient: from 0.1Ib to Imax at unity PF; from 0.2Ib to Imax at unity 0.5 lagging<0.08%/°C<0.12%/°C 15. Insulation level: withstand AC voltage for 50Hz, 1min withstand impulse voltage 1.2/50us>2kV (when bakelite base>4kV)>6kV (when bakelite base>8kV) 16. Rated load torque at unity PF, Ib 450uNm 17. Meter base bakelite or steel 18. Meter cover bakelite or transparent PC 19. Terminal cover bakelite or PC
