Three-phase static active watt-hour meter is designed for measuring active energy by connecting to industrial power supply system, which has firm structure, good appearance and wide practicability. It has high reliability for the adoption of large-scale integrating and SMT technology . We can design the meter with different functions according to user requirement, so it can be wildly utilized in transmission & distribution system and Automatic meter reading system.
