Abstract: It is necessary to improve the testing method for the protection relay in digital substations as its hardware and signal
processing are different from that of the traditional relay based on puter. Analyzing the testing requirements, available
schemes, this paper discusses the function and consistency testing methods of the digital protection device in laboratory. In addition,
its configuration and testing scheme in engineering practice are also analyzed, pointing out that there is insufficiency in the current
instruments such as unable to test the performance of protection devices in abnormal states, and, for most of them, to receive IRI
