| 摘 要： | 针对变压器保护投运时，用六角图法检查变压器各侧电流互感器二次回路正确性时存在的不足，提出用功率平衡结合六角图法检查回路的正确性。该方法能比较全面地检查电流互感器二次回路，而且简单可靠。文章详细论述了这种改进方法．并用实例验证了这一方法的可用性。 |

| Abstract: | There is the deficiency when we use the six-angle-chart method to examine the secondary circuit of current transformer in the process of putting transformer protection into function. This article puts forward a new method that combines the power balance principle with the six-angle-chart method. The new method can examine the secondary circuit of current transformer roundly, simply and reliably. This article discusses the improved method in detail andvalidates the usability by an example. |
