Description

technical field [0001] The invention relates to the field of power systems, in particular to an inspection system of a relay protection device. Background technique [0002] A relay protection device is a device in which one or more protection elements and logic elements are combined according to requirements to complete a specific protection function in the current system. [0003] When the power components or power system in the power system fail to endanger the safe operation of the power system, the relay protection device can send an alarm signal to the operating personnel on duty, so that the monitoring terminal can prevent further deterioration of the event through automatic or manual methods. [0004] In the prior art, equipment including relay protection testers, ammeters, high-power rheostats, wave recorders and other equipment are generally used to test the performance of relays. The wiring of these equipment is cumbersome and inefficient, and it is not conducive ...
