摘要：
Based on the analysis of a 110kV digital substation main transformer differential protection action situation, pointing out that the malfunction cause of the trip, give out the improvement program, improve the understanding of the GPS in the digital, and recognize the the importance of intelligent substation. Provides a theoretical and application for the proper preparation of the same type of protection device, thus effectively avoid the protection device in the series malfunction again.
