Background
The electroscope is an instrument for detecting whether an object is charged or not and roughly estimating the charged quantity, and is widely applied to a power system. When the line is overhauled and the switching operation is carried out to hang and connect the electric wire, an electroscope is needed to be used for detecting whether the line is electrified or not. After the power failure is confirmed, the wire is contacted with the ground by using the grounding rod, so that the current can be smoothly discharged into the ground. The worker can then perform the operation of hanging the electric wire. The current electroscope withdraws the electric wire after the electricity testing is completed, and can not monitor the live condition of the cable in real time. Therefore, the reverse power transmission phenomenon of the cable is likely to occur in the period from the beginning to the completion of the operation, and thus great personal safety risk is brought to workers hanging the ground wire.
