| 摘要: |
| 中阻母差以结构简单、动作快速、抗ＴＡ（电流互感器）饱和等特点，在高压电网中得到广泛应用，掌握其动作行为对整定、调试、运行、事故分析有一定的实际意义。从正常运行，区内、外故障，ＴＡ深度饱和，部分饱和，母联ＴＡ的使用等几个方面作了详细分析。 |

| Abstract: |
| Middle impedance bus differential protection is widely used in high voltage power network for its simple structure, fast response, TA saturation resistant, and etc. It is practical to understand its behavior for setting, commissioning operation and fault analysis. Detail analysis is given for normal operation internal and external fault, TA partial and fully saturation and bus coupler TA application. |
| Key words: bus protection,behavior,fault analysis, |
