Description

The HLD01 (DD862) single-phase meter is designed to meet the IEC60521-1988 and BS EN 60521 standards for both indoor and outdoor installations. The meter with mechanical construction complying BS5685 is also available. With accuracy of class 2, it measures active energy in single-phase two-wire or three-wire alternating current power grids. Connection is direct or by instrument transformers. The average service life (MTTF) is 10 years and the maximum overload capacity is 500%Ib. The meter is KEMA certified and the design can be tailored to different customer requirements.

1. Meter case
Two types of cases are available. One is the insulating case of protective-class II and the other is the weather-proof case complying to IEC60529 and IP54.

2. Terminal block
The terminal block is molded of Bakelite. The voltage test link can be located inside or outside of the meter case. The maximum diameter of the terminal hole is 8. 5mm.

3. Driving element
The driving element consists of a voltage element and a current element, both of which are fixed to the frame. The voltage element has a low load adjustment mechanism, and the current element has an inductive load adjustment mechanism.

4. Rotor
The rotor shaft is made of aluminum alloy with a small hole in the upper end for storing lubrication and for fitting a brass bearing. The worm is turned of brass, and is acid-cleaned or nickel-plated. The worm and shaft can be detached.

5. Braking element
The magnet is made of AlNiCo5 alloy and designed as U-shaped so that the effect of short-time over current upon the magnet is negligible. The full load error can be fine controlled by adjustment mechanism.

6. Frame
The frame is die-casted by high-quality Si-Al alloy of stable property to avoid distortion. The application of static spray-painting on the surface prevents the frame from oxidation.

7. Upper bearing
The pin is made of high-quality abrasion-proof stainless steel and is embedded On the brass
