变压器差动保护试验方法

Test method for transformer differential protection

差动保护是变压器内部故障的主保护之一,为了有效提高变压器保护动作的正确率,通常用比率制动式差动保护作为变压器的主保护,因此,对变压器差动保护方法进行研究。

Differential protection is one of the main protections of the transformer internal fault. In order to improve the correct rate of transformer protection action,the differential protection of the transformer is usually used as the main protection of the transformer. Therefore,the differential protection method of the transformer is studied.
