Generally, power is transferred from a power plant to a substation, subjected to several stages of transforming process, and then transferred to a home through a pole transformer along a distribution line such as a concrete pole.
In this case, the distribution line installed on the main pole requires securing materials and good grounding in the distribution line in order to protect the equipment by abnormal voltage such as lightning and surge and to prevent various electric disasters due to electric leakage.
The ground has the function of protecting human and electric equipment from power or lightning.
Particularly, in each complex of the apartment house, a distribution unit such as a distribution box is installed, and a distribution line is also installed.
Conventionally, since the state of grounding in each of the power distribution parts of each complex can not be monitored in real time, there is a problem that an electric shock accident occurs when an earth fault occurs in the power distribution part of any one complex.
A prior art document related to the present invention is Korean Patent Registration No. 10-0869084 (November 11, 2008).
