A grounding device comprising: a fixed electrode connected to the cable head; a grounding electrode disposed opposite to the fixed electrode within the cable head container; a main circuit side electrode connected to the main circuit conductor; and a main circuit side electrode having a length that can simultaneously contact the fixed electrode, the main circuit side electrode, and the ground electrode, and the fixed electrode, the main circuit side electrode, and the ground electrode. A movable electrode provided so as to be able to be displaced between a grounded position in which it simultaneously contacts and a non-grounded position in which it contacts only the grounded electrode, and an operating means for operating the movable electrode from outside the cable head container. A grounding device for testing gas insulated switchgear.
