摘　　要：电力系统中，由于各种原因引起三相电流的不平衡，就可能造成对机器设备、仪器仪表等重要设备的损坏。文章首先通过分析电力系统中引起电流不平衡的原因，进而说明了研究三相电流不平衡的必要性，设计了三相电流在线检测装置，实现三相电流的在线监测。In power system, due to various causes of three-phase current imbalance, it could result in machinery and equipment, instruments, and other important equipment damage. By analyzing the reasons of the current imbalance in the power system, it＇s shown that it is necessary for studying the three-phase current imbalance to design three-phase current online detection devices, and to achieve the three-phase current online monitoring.
