2.Function and application:
Overhead pole mounted primary metering unit complies with the latest applicable industrial standards and local and or national electrical code (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 so as to reduce losses.
