What Is The Working Principle Of Mechanical KWH Meter

We can see the watt-hour meter in some very small corners in our daily life. Although we will not notice it, we will check it when we pay the electricity bill.

We can see the watt-hour meter in some very small corners in our daily life. Although we will not notice it, we will check it when we pay the electricity bill. Therefore, it is very important to have an accurate watt-hour meter. Importantly, mechanical kWh meter is a good choice, so do you know how it works?

In the mechanical kWh meter, the voltage circuit and the current circuit are separated. The voltage circuit provides an alternating electric field, and the current circuit provides an alternating magnetic field. The two alternating fields generate driving force on the aluminum plate owing to the middle to make it rotate. This is The working principle of a mechanical electric energy meter.

When the electric energy meter is connected to the circuit under test, an alternating current is generated in the current coil and the voltage coil. These two alternating currents respectively produce alternating magnetic fluxes in their iron cores. The AC magnetic flux passes through the aluminum plate and induces eddy currents on the aluminum plate. The eddy current is forced in the magnetic field to make the aluminum plate rotate through the rotating cabinet.

For mechanical kWh meter and single phase energy meter , the working principle is the same, and even the function is the same. Although there will be some differences in functions, in fact, the difference is not very big.
