一、什么是三相电表？
三相电表用于测定额定频率为5OHZ，参比电压为3×220/380V的三相四线制交流有功电能。该表基架采用优质铝合金压铸而成，并经过时效处理，具有良好的稳定性，采用双宝石转动轴承，减小了磨擦力矩，计度器转动轴两端来用宝石结构转动更为灵活，采用高矫顽力合金永磁磁钢，性能更加稳定。
二、如何选择三相电表型号规格?
如果是小型工厂、商业门面或居民建筑，这种场合的用电电压是200V/380V，如果电流在100A以下，建议选择1.0级精度的三相电能表；如果用电设备有电动机，需要选择1.0级精度的三相智能电表，因为使用电动机的负荷，电量有损耗，普通电子表计量不出复杂的电量损耗波形。如果是大中型工厂的车间，电流一般都超过100A，需要使用带电流互感器接入式电能表，三相智能电表精度应达到0.5S级，这种场合的用电电压也是200V/380V。
