基于比率制动原理的变压器差动保护测试方法

Test method of transformer differential protection based on ratio brake principle

针对目前大型变压器差动保护广泛采用比率制动的原理,以国电南京自动化股份有限公司生产的DGT801系列数字式发电机变压器组保护装置为例,说明保护的测试方法。

For the transformers differential protection widely uses the ratio brake principle,this paper presents a example：DGT801 generating plants and transformers banks protection system based on microcontroller made in the State Grid Nanjing Automation Co.,Ltd.,and introduces the test methods for the protection systems.
