1. General The HLD06 single-stator meter is a socket type meter designed to meet the latest ANSI C 12.1 and ANSI C 12.10 standards. The meter measures active energy in single-phase two wire or three wire alternating current power grids and 60Hz. Connection is FM 1S and FM 2S. It is a reliable long service life meter. The average service life (MTTF) is 30 years and the maximum current is 200A. Both cyclometer type and clock type registers are available. In addition, it can be equipped with an AMR module. 2. Construction 2. 1 Meter Case The socket type meter case complies with ANSI C 12.7-1993 and meets the protection requirements set by ANSI C 12.10-1993. 2. 2 Driving Element The driving element consists of a voltage element and a current element, both of which are fixed on the aluminum alloy frame. It has a load curve compensation mechanism and an inductive load adjustment mechanism. 2. 3 Rotor The worm is an undetachable part of the shaft so that the mesh between the worm and shaft is improved. Both ends of the shaft are embedded with a graphite bearing to ensure the long service life of the meter. 2. 4 Upper Bearing The upper bearing is magnetic suspension bearing with a guide pin and an aluminum sleeve. 2. 5 Lower Bearing The lower bearing consists of a guide pin and a brass sleeve, and is fixed into the meter frame by one screw. 2. 6 Braking Element Two magnet cubes are die-casted into the meter frame by aluminum alloy. It has a temperature compensation plate inside. 2. 7 Frame The frame is die-casted by high quality SiAl alloy of stable property to avoid distortion. It has both full load and low load adjustment mechanisms. 2. 8 Register There are two register types: Clock type and Cyclometer type. The register has 5 dials or 5 drums. Both Bi-directional or Unidirectional registers are available. 3.
