Overhead pole mounted primary metering unit Comply with the latest applicable industry standards and local and/or national electrical regulations (such as IEC, IEEE (ANSI), CAN, GOST, CEF). It is used for three-phase overhead power grid energy measurement management and distribution network automation management system. The primary side measurement is more accurate, and the power loss of the line can be effectively measured to reduce losses.
