Power meters are power measurement and control equipment that provide solutions for power parameter measurement, power quality monitoring and analysis, and electrical equipment control.

The main power meters on the market are: pointer meter, Mechanical electric energy meter, multi-function meter, and smart IoT energy meter.

Pointer table

It works with the principle of magnetoelectricity, drives the pointer to move, and relies on the position of the pointer on the panel to display the size of the measured parameter. The background of the times determines its existence, and its advantages are easy installation and low cost.

  Mechanical electric energy meter

 The working principle of the mechanical electric energy meter is: when the electric energy meter is connected to the circuit, the magnetic flux generated by   the voltage coil and the current coil passes through the disk. These magnetic fluxes are out of phase in time and space, and eddy currents are induced on   the disk respectively. , Due to the interaction between the magnetic flux and the eddy current, the rotating torque is generated to make the disc rotate. Due   to the braking effect of the magnetic steel, the rotation speed of the disc reaches a uniform motion. Because the magnetic flux is proportional to the voltage   and current in the circuit, the circle Under its action, the disc moves at a speed proportional to the load current. The rotation of the disc is transmitted to the   counter through a worm, and the indication of the counter is the actual electric energy used in the circuit.

 With the development of the electronics industry, electronic energy meters are becoming more and more mature. In order to facilitate human-computer   interaction, realize large-screen multi-data display, etc.

 Its advantage is that it displays data more intuitively and generally has a communication interface.

Multi-function meter

The smart meter is the smart terminal of the smart grid. It is no longer an electric energy meter in the traditional sense. In addition to the basic power metering function of the traditional electric energy meter, the smart meter also has more functions, such as RS485 remote communication and remote signaling. , Remote control, multiple rate measurement, power quality analysis, fault recording, trend curve, etc.;

Intelligent terminal (Internet of things power meter)

With the development of emerging technologies of the Internet of Things, more and more applications such as edge intelligence, wireless communication, and Internet of Things protocols are being used. Smart meters follow the trend, apply IoT technology, and develop into today's smart terminals (IoT power meters).

Reviewing the development of Heyuan Electric Power Meters, we have experienced the first generation of digital display meters, the second generation of multi-function meters, and the third generation of electric energy meters, and finally combined 20 years of electric power experience and the latest technology of the Internet of Things, and fully integrated the power supply data. The acquisition, calculation, analysis and early warning of azimuth, launched the industry's first holographic electric IoT intelligent terminal-HYFW.
