Although traditional relay protection systems can play a certain protective role, they have some limitations, such as the inability to comprehensively monitor the power system and the lack of accurate judgment. In industrial and utility power systems, proper protection relay coordination is essential to ensure that only the faulted section is isolated — without causing unnecessary shutdowns or widespread blackouts. As technology advances and grids become smarter, the tools used to test and maintain these systems, such as the relay test set, are evolving to meet new challenges. Developing and applying intelligent relay protection systems has become an important way.
