Although almost every household is now equipped with electric meters, not all residents know about electric meters. So do you know what a three phase meter is? How much do you know about three phase meter?
The three phase meter, as the name implies, is an electric meter that mainly detects three-phase alternating current. The three-phase alternating current is a kind of electric energy transmission method, generally referred to as three-phase electricity. It is a power supply composed of three AC potentials with the same frequency, the same amplitude, and the phases differing by 120°. It has a wide range of uses. It is mainly used in AC power equipment in the industry, such as motors, which use three-phase AC, which is the three-phase four-wire system we often mention. In daily life, when lighting electricity is used for power supply, one of the three-phase electricity is used to supply power to the electrical equipment, such as household appliances, and the other wire is the fourth wire among the three-phase four-wire. It is the neutral line, which is drawn from the neutral point of the three-phase power.
The above is a brief introduction to three-phase electric meters. Most electric meters have the same functions and functions, but with some additional functions, and theElectromechanical KWh Meter is no exception. yhddb.com
