I believe everyone has a certain understanding of single-phase electric meters, but I wonder if you have heard of auxiliary the single phase electromechanical kwh meter ?
We all know that most single-phase electric meters are household electric meters and single-phase electromechanical kWh meters agree that they are mostly used for household use. Single-phase electromechanical kWh meter is applied to active power measurement: accurate measurement, modular and small size, can be easily installed in various terminal distribution boxes. Rail type installation, bottom wiring, perfect match with miniature circuit breaker. The intuitive and easy-to-read mechanical display reduces the risk of data loss due to accidental power failure. No external power supply is required. Wide operating temperature range. The watt-hour meter uses the eddy current generated by the voltage and current coil on the aluminum plate to interact with the alternating magnetic flux to generate electromagnetic force, which makes the aluminum plate rotate, and at the same time introduces the braking torque, so that the aluminum plate speed is proportional to the load power. It is driven by gears, and the number of rotations of the turntable is calculated by the counter to measure the electric energy.
However, the three phase electromechanical kwh meter is also mostly used in households.
