They can effectively prevent the expansion of power system accidents and ensure the stable operation of the power grid and the reliability of power supply.

[0003] The rapid development of the power system continuously poses new requirements for relay protection devices. The usage of relay protection has increased significantly, and the shipments of relay protection manufacturers have also increased accordingly. With the growth of production capacity, a large number of testers are required for the wiring test of functional tests in relay protection testing. The wiring is cumbersome and error-prone, wasting a large amount of labor costs. Each relay protection needs to be wired and tested for different function tests. First, the relay protection device needs to be installed on the test fixture, and then the wiring between the test fixture and the test bench needs to be completed. Since it is an artificial operation and the energy is limited, it is inevitable for the tester to make mistakes and miswire during wiring, resulting in damage to relay protection components. Follow-up repairs and reassembly are also required, which is time-consuming and laborious, wasting a large amount of human resources, increasing the production cost for enterprises, and affecting the work progress.
