FIG. 1B illustrates a conventional detector when the insulating rod 10 is folded by using the first joint 60 and the second joint 70.

Before using the conventional detector to work on the substation equipment and the transmission tower, it is first determined whether a current flows on the wire. When the connection bracket 20 is connected to an electric wire, the detection unit 40 determines whether a current flows, and when the current flows, emits light or emits a sound through the sound unit 50.

On the other hand, the conventional grounding device is composed of a pair of insulating rods and a ground wire as shown in FIG. Insulation rod is composed of a ground rod 130 in a multi-stage, S-shaped clasp 110 is coupled to the end. The clasp 110 and the ground rod 130 is coupled to the connector 120 and the like.

The ground wire is provided with a steel tower side bracket 210 coupled to a steel tower or ground at one end thereof, and a wire side bracket coupled to a wire is provided at the other end thereof.
