What is a 3-Phase Smart Energy Meter?

A 3-phase smart energy meter is a device used to measure the energy consumption in a 3-phase alternating current (AC) circuit. It is widely used in industries, commercial establishments, and residential electricity systems, serving as an essential tool for energy measurement and management. This article provides a detailed introduction to the 3-phase smart energy meter.

Basic Principles of the 3-Phase Smart Energy Meter

The 3-phase smart energy meter operates based on the principle of electromagnetic induction for energy measurement. It consists of a current coil, voltage coil, a rotating disk, and a counter. When the current and voltage in a 3-phase AC circuit pass through the current and voltage coils, a magnetic field is generated. This magnetic field acts on the permanent magnet in the rotating disk, causing it to spin. The rotational speed of the disk is proportional to the power in the circuit. The number of rotations is recorded by the counter, allowing the calculation of the energy consumption in the circuit. Furthermore, its principle is based on Faraday's law of electromagnetic induction and the watt law, which enables the measurement of energy through the superposition of induced electromotive force and the generation of a rotating magnetic field.
