摘要
三相低压电能计量用户必须根据用电大小安装合适规格的三相电表,容量更大的用户还必须安装电流互感器,这些用电计量环境存在管理难度大、计量设备复杂的问题,偷电漏计量情况时有发生,电流规格为2(200)A的大电流三相电表的使用能够统一电表规格,简化检表、配送、安装维护的工作量,同时增加恶意偷窃电的难度,提高了计量设备和系统的可靠性。
Low-voltage metering power custom must install the appropriate specifications of three-phase meters based on the electricity quantity. Larger capacity custom must also install the current transformer （CT）,which will bring difficulty in the management and the metering equipment. Moreover, the phenomenon of electricity stealing and leakage of metering will often occur. The 2（200）A three-phase meters could unify the specifications of meters, simplify the workload of inspecting meters, distribution, installation and maintenance,and increase the difficulty of electricity stealing as well as improve the reliability of metering equipment and system.
