  With the rapid development of my country's economy, the demand for electricity in all walks of life is increasing, and various electric meters have appeared accordingly. Electromechanical KWh Meter is also one of them. So today we will talk about watt-hour meters.

  The watt-hour meter can be divided into a DC watt-hour meter and an AC watt-hour meter according to the circuit used. For example, the power supply in our home is AC, so it is an AC watt-hour meter. AC watt-hour meters can be divided into single-phase watt-hour meters, three-phase three-wire watt-hour meters, and three-phase four-wire watt-hour meters according to their circuits. Households with large electricity consumption also use three-phase four-wire watt-hour meters, and industrial users use three-phase three-wire and three-phase four-wire watt-hour meters.

  The "current coil" has a thicker wire and fewer turns. Because it is connected in series with the load (that is, the appliance that uses electricity), the load current flowing in it is also called the use current. When the load is electric heaters and incandescent lamps and other electrical appliances that use the thermal effect of current to work, the load current does not lag behind the power supply voltage. Moreover, the lines of magnetic force at this time are also generated simultaneously with the change of the load current.

  For example, three phase meter is more commonly used in households.
