The present invention relates to an inspection system for a GF relay. A display, a plurality of connection terminals for manual measurement, and a relay socket, wherein a GF relay is connected are included in a casing. An inspection unit which is embedded in the casing is connected to the connection terminals and the relay socket for manual measurement. The inspection unit is installed so external power is supplied and the operation time according to the ascending and descending of a relay, contact point resistance, and operation voltage are measured. According to the present invention as above, the use of new and used relays can be possible and an optimum operation can be possible by accurately grasping the contact point resistance, the voltage, and the operation time of the relay. Early destruction of the relay can be prevented by controlling a failure of the operation time. Automatic and selective measurements and a measurement by hand can be possible and an accurate point of a contact failure can be grasped. 본 발명은 디스플레이와 복수의 수동측정용 연결단자 및 GF계전기가 접속되는 계전기소켓이 케이싱에 구비되고, 상기 연결단자 및 계전기소켓에는 케이싱에 내장되는 검사유니트가 연결되며, 상기 검사유니트는 외부전원이 공급토록 설치되면서 계전기의 강상 및 낙하에 따른 동작시간과 접점저항, 동작전압을 측정토록 설치되는 GF계전기용 검사시스템에 관한 것이다.
