Abstract: An example of the present disclosure provides a protective relay inspection device including: a connection unit connected to a protective relay; and an inspection unit which, upon receiving a relay setting-providing signal including relay setting information for the protective relay via the connection unit, processes an inspection of a relay function of the protective relay on the basis of the relay setting-providing signal. Here, the inspection unit includes: a plan generation unit which generates inspection plan information for an automatic inspection function on the basis of the relay setting-providing signal; and an inspection processing unit which inspects the relay function of the protective relay on the basis of the inspection plan information.
