In life, the use of electrical appliances such as mobile phones, computers, televisions, or the "little sun" in winter cannot be separated from the support of electric energy, so electric energy occupies a very important place in our lives. With electric energy, an electric watt-hour meter, such as a three phase meter , must be available.

The accuracy level of the three-phase meter is 1.0; the rated voltage is 3×57.7/100V, 3×220/380V, 3×380V; the basic current is 1.5(6)A, 5(20)A, 10(40)A, 15(60)A, 20(80)A, 30(100)A; rated frequency is 50Hz; environmental conditions are working temperature -25℃～+55℃; limit working temperature is -20℃-50℃; starting current is ≤0.5%Ib; the external dimension is 279.5*172*124mm; the relative humidity is ≤85%; the power consumption of the electric meter is <2W8VA; the executive standard is GB/T15283-1994, GB/T15282-1994. The three-phase electric meter is for fixed installation indoors. It is suitable for the environment, and the air does not contain corrosive gas and avoids dust, mold, salt spray, condensation, insects, etc. Before adjusting the three-phase watt-hour meter, remember that it must be checked before it can be used.

In addition to the three-phase watt-hour meter, the Electromechanical KWh Meter is also a very good watt-hour meter, and the electromechanical KWh Meter combines the functions of a mechanical watt-hour meter and an electronic watt-hour meter. In general, two The watt-hour meters are very practical and durable.
