Single Phase Electro-Mechanical Power Meter (DD862)

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 /><
