In a family, in addition to electrical appliances, household appliances, etc., the most concerned about the construction of water and electricity, that is, we pay monthly, quarterly or annual water and electricity bills, but most of them should be paid monthly. We often hear some family members and friends talking about three-phase electricity and three phase electricity meter when talking about electricity bills. So what is a three phase electric meter?
Three-phase electric meter is a general term for electric meters, which can be used to measure voltage, current, etc. It is also an abbreviation for electric energy meter. It is an instrument used to measure electrical energy. It is also called an watt-hour meter, fire meter, electric energy meter, kilowatt-hour meter, and even an electric meter that measures various kinds of electricity.
The working principle of a three-phase electric meter is a three-phase four-wire active and reactive energy meter. The electromagnetic element is an independent structure, and the voltage movement adopts a fully perforated closed sample movement. The rotating system is statically balanced, the bearing is a double jewel structure with shockproof springs, the damping element is made of Alcobalt 34 electromagnetic steel, and the thermomagnetic alloy sheet is used for temperature compensation. The watt-hour meter is produced by moving the voltage and current components into the magnetic field, so that the disc rotates under its action, and the disc speed is proportional to the magnitude of the load current, so as to achieve the purpose of measuring electric energy.
Of course, there can be no easy-to-use three phase electricity meter on the market. The kilo watt-hour meter is also a good meter.
