Uses and structural features of three phase electric meters


The three phase electric meter is used to measure the three phase four-wire AC active energy with a rated frequency of 50HZ and a reference voltage of 3×220/380V. The base frame of the three phase electric meter is made of high-quality aluminum alloy die-casting and has undergone aging treatment. It has good stability. The double-jewel rotating bearing is adopted to reduce the frictional moment. For flexibility, high-coercivity alloy permanent magnet steel is used to make the performance more stable. The three phase electric meter has the advantages of strong overload capacity, good error linearity, stable quality, design service life up to 15 years, and reliable performance.
