摘　　要：介绍了GRT 100型数字式变压器保护的特点以及在动模试验中发现的问题,并对用该型号保护替换宝钢能源部原有变压器保护进行了适用性研究,对于GRT 100保护的应用具有一定的实际意义,另外,也为在采用数字式保护替换模拟式保护中需要注意的问题进行了一些有益的探讨。The features of GRT-100 digital transformer protection and the problems found in its dynamic model test were introduced. The applicability research was conducted on replacing the existing transformer protection in Bao Steel Power Plant with GRT-100 digital transformer protection, which has a practical meaning to the application of GRT-100 protection. Problems that should be noted in applying digital type protection to replace analog type protection were also discussed.
