| Abstract: | Merging unit is important equipment in intelligent substation to transmit digital sample values, which is related to the correctness of protection action. This article describes the secondary signal acquisition method in intelligent substation and analyzes the causes for the merging unit delay. In the final, the paper proposes to detect the merging unit delay by using the analog and digital output from relay protection tester. |
